[0005] Patent Literature 1: Japanese Patent Application Publication No. 2004-201018 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] The dielectric resonator antenna disclosed in Japanese Patent Application Publication No. 2004-201018 has a configuration in which the power feeding line contacts the side surface of the dielectric block, but has a problem in that it is not easy to support the dielectric block in a direction along the mounting surface of the substrate. Specifically, the power feeding line contacting the side surface of the dielectric block is merely an elongated conductor extending in a straight line shape, and thus there is a concern that the dielectric block cannot be sufficiently supported in the direction along the mounting surface of the substrate.

[0008] The present disclosure was made to solve the above-described problem, and aims to achieve support of a dielectric block and power supply to the dielectric block in a dielectric resonator antenna.

[0009] SOLUTION TO PROBLEM

[0010] The antenna device of the present disclosure includes a substrate formed with a ground electrode and a power supply wiring, a dielectric block disposed on a mounting surface of the substrate and having a side surface intersecting the mounting surface, and a plate-shaped first frame made of metal disposed on the mounting surface. The first frame has a first main body portion disposed at a position separate from the dielectric block, and a first protruding portion protruding from the first main body portion toward the dielectric block. The first protruding portion includes a first terminal portion disposed at a top end of the first protruding portion and having a first abutting surface abutting the side surface of the dielectric block, and a first wiring portion disposed between the first main body portion and the first terminal portion. When a normal direction of the mounting surface is set as a first direction, the first abutting surface extends along the first direction and opposes the side surface of the dielectric block. The first wiring portion is connected to the power supply wiring.

[0030] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Furthermore, the same or equivalent parts in the drawings will be labeled with the same reference numerals, and their descriptions will not be repeated.

[0031] (Basic structure of a communication device)

[0032] Figure 1 This is a block diagram of a communication device 10 using the antenna device 120 of this embodiment. The communication device 10 is, for example, a mobile phone, a smartphone, a tablet computer, or a personal computer with communication capabilities. One example of the frequency band of the radio waves used in the antenna device 120 of this embodiment is millimeter-wave radio waves with center frequencies such as 28 GHz, 39 GHz, and 60 GHz, but radio waves in other frequency bands can also be used.

[0033] Reference Figure 1 The communication device 10 includes an antenna module 100 and a BBIC 200 constituting a baseband signal processing circuit. The antenna module 100 includes an RFIC 110 (as an example of a power supply device) and an antenna device 120. The communication device 10 up-converts the intermediate frequency (IF) signal transmitted from the BBIC 200 to the antenna module 100 into a high-frequency signal and radiates it from the antenna device 120. It also down-converts the high-frequency signal received by the antenna device 120 into an IF signal and processes the signal using the BBIC 200.

[0034] The antenna device 120 includes a flat substrate 130 having a generally rectangular shape and a plurality of dielectric blocks 121 disposed on a mounting surface 130a of the substrate 130. Figure 1The diagram shows an example of an array structure in which four dielectric blocks 121 are arranged in a row on the mounting surface 130a of the substrate 130, but the number and arrangement of dielectric blocks 121 are not limited to this. Individual dielectric blocks 121 can be arranged on the mounting surface 130a of the substrate 130, or more than five dielectric blocks 121 can be arranged. Alternatively, it can be an array structure in which the dielectric blocks 121 are arranged in two dimensions.

[0035] When a high-frequency signal of a predetermined frequency band is supplied to the dielectric block 121, the electric field resonates inside the dielectric block 121, and the electromagnetic wave corresponding to the resonant frequency radiates outward from the dielectric block 121. That is, the antenna module 100 is a dielectric resonator antenna (DRA). The resonant characteristics (corresponding frequency band) of the dielectric block 121 are determined by the shape and size of the dielectric block 121 and the dielectric constant of the dielectric materials constituting the block.

[0036] In the antenna module 100 of this embodiment, a high-frequency signal from the corresponding power supply wiring 140 is supplied to each dielectric block 121. The antenna module 100 is a so-called single-band single-polarization antenna module.

[0037] RFIC 110 includes switches 111A-111D, 113A-113D, 117, power amplifiers 112AT-112DT, low-noise amplifiers 112AR-112DR, attenuators 114A-114D, phase shifters 115A-115D, signal synthesizer / distributor 116, mixer 118, and amplifier circuit 119.

[0038] When transmitting high-frequency signals, switches 111A-111D and 113A-113D switch to the power amplifiers 112AT-112DT, and switch 117 is connected to the transmitting amplifier of amplifier circuit 119. When receiving high-frequency signals, switches 111A-111D and 113A-113D switch to the low-noise amplifiers 112AR-112DR, and switch 117 is connected to the receiving amplifier of amplifier circuit 119.

[0039] The intermediate frequency signal transmitted from BBIC 200 is amplified by amplifier circuit 119 and up-converted by mixer 118. The up-converted high-frequency transmission signal is split into four signals by signal synthesizer / distributor 116, and each signal is powered to a different dielectric block 121 through a corresponding signal path. By adjusting the phase shift of phase shifters 115A to 115D configured in each signal path, the directionality of the electromagnetic wave output from dielectric block 121 can be adjusted. In addition, attenuators 114A to 114D adjust the strength of the transmitted signal.

[0040] The received signals, which are high-frequency signals, received by each dielectric block 121 are transmitted to the RFIC 110 and combined in the signal synthesizer / distributor 116 via four different signal paths. The received signals obtained by combining are down-converted to intermediate frequency signals by the mixer 118, and then amplified by the amplifier circuit 119 before being transmitted to the BBIC 200.

[0041] RFIC 110 can be formed as a single-chip integrated circuit component, for example. Alternatively, for devices corresponding to each dielectric block (switches, power amplifiers, low-noise amplifiers, attenuators, phase shifters), it can also be formed as a single-chip integrated circuit component for each corresponding dielectric block.

[0042] (Construction of the antenna module)

[0043] Next, use Figure 2 and Figure 3 This describes the detailed structure of the antenna device 120. Figure 2 This is a three-dimensional view of antenna device 120. Figure 3 The diagram is obtained by locally magnifying the periphery of a dielectric block 121 of the antenna device 120.

[0044] Furthermore, in the following description, the normal direction of the mounting surface 130a of the substrate 130 will be defined as the Z-axis direction, the direction along the short side of the mounting surface 130a will be defined as the X-axis direction, and the direction along the long side of the mounting surface 130a will be defined as the Y-axis direction. In the figures, there are cases where the positive direction of the Z-axis is referred to as the upper side and the negative direction as the lower side.

[0045] The dielectric block 121 has a cuboid (more specifically, a regular square prism) shape. However, the dielectric block 121 can be any prism shape, and is not necessarily limited to a cuboid shape. For example, the dielectric block 121 can also be cylindrical.

[0046] like Figure 2 As shown, in addition to the four dielectric blocks 121, a plurality of plate-shaped metal frames 150, 160, 170, and 180 are disposed on the mounting surface 130a of the substrate 130. For each dielectric block 121, one frame 150, 160, 170, and 180 are respectively disposed.

[0047] The substrate 130 may be, for example, a low-temperature co-fired ceramic (LTCC) multilayer substrate, a multilayer resin substrate formed by stacking multiple resin layers composed of resins such as epoxy resin and polyimide resin, a multilayer resin substrate formed by stacking multiple resin layers composed of liquid crystal polymer (LCP) with a lower dielectric constant, a multilayer resin substrate formed by stacking multiple resin layers composed of fluorine-based resins, a multilayer resin substrate formed by stacking multiple resin layers composed of PET (polyethylene terephthalate) material, or a ceramic multilayer substrate other than LTCC. Alternatively, the substrate 130 may not necessarily be a multilayer structure and may be a single-layer substrate.

[0048] A flat-shaped ground electrode GND is disposed on the lower surface of the substrate 130. In addition, the ground electrode GND is not necessarily limited to being disposed on the lower surface of the substrate 130, but may also be disposed on the middle layer of the substrate 130, or on the mounting surface 130a (upper surface) of the substrate 130.

[0049] Dielectric block 121 is disposed on the mounting surface 130a of substrate 130. Therefore, dielectric block 121 is disposed opposite to ground electrode GND. In this configuration, when a high-frequency signal is input (powered) to dielectric block 121, electromagnetic waves are radiated from dielectric block 121 in the direction opposite to ground electrode GND. Furthermore, the resonant frequency of dielectric block 121 depends on the length of the edge of the top surface of dielectric block 121, and the bandwidth of dielectric block 121 depends on the height of dielectric block 121 (dimension in the Z-axis direction).

[0050] The power supply wiring 140 is disposed in the middle layer of the substrate 130. In addition, the power supply wiring 140 is not necessarily limited to being disposed in the middle layer of the substrate 130, for example, it can also be disposed in the mounting surface 130a (upper surface) of the substrate 130.

[0051] One end of power supply cabling 140 connects to RFIC 110 (see reference). Figure 1 The other end of the power supply wiring 140 is connected to the power supply point SP disposed on the mounting surface 130a of the substrate 130 via a passage or the like.

[0052] Reference Figure 3 This illustrates the structure of frames 150, 160, 170, and 180.

[0053] The frame 150 has: a main body 151 disposed at a position separating from the dielectric block 121 in the positive Y-axis direction; and a protrusion 154 protruding from the main body 151 toward the dielectric block 121 in the negative Y-axis direction. The main body 151 is connected to the ground electrode GND via a passage 141.

[0054] The protrusion 154 includes: a terminal portion 152 disposed at the top of the protrusion 154; a wiring portion 153 disposed between the main body portion 151 and the terminal portion 152; and a branch portion 155 branching from the wiring portion 153.

[0055] The terminal portion 152 has a surface that abuts against the side surface 121a of the dielectric block 121. The surface of the terminal portion 152 that abuts against the side surface 121a (hereinafter also referred to as the "abutting surface of the terminal portion 152") extends in the positive Z-axis direction and is opposite to the side surface 121a of the dielectric block 121.

[0056] The wiring portion 153 extends along the Y-axis, with one end connected to the main body portion 151 and the other end connected to the terminal portion 152. The dimension of the wiring portion 153 in the Z-axis direction is smaller than the dimension of the terminal portion 152 in the Z-axis direction. The terminal portion 152 is bent at approximately 90° relative to the wiring portion 153.

[0057] Branch 155 branches off from wiring section 153 and extends along the X-axis, with its top end connected to power supply point SP. Thus, wiring section 153 connects to power supply wiring 140 at a position closer to terminal section 152 than to the connection portion connected to main body section 151. Alternatively, branch 155 can be omitted. When branch 155 is omitted, wiring section 153 can simply connect to power supply point SP at a position closer to terminal section 152 than to the connection portion connected to main body section 151.

[0058] The frame 160 includes: a main body 161 disposed at a position separating from the dielectric block 121 in the negative X-axis direction; and a protrusion 164 protruding from the main body 161 toward the dielectric block 121 in the positive X-axis direction. The protrusion 164 includes: a terminal portion 162 disposed at its top end, having a surface abutting against the side surface 121a of the dielectric block 121; and a wiring portion 163 disposed between the main body 161 and the terminal portion 162. The surface of the terminal portion 162 abutting against the side surface 121a (hereinafter also simply referred to as the "abutting surface of the terminal portion 162") extends in the positive Z-axis direction and faces the side surface 121a of the dielectric block 121. The dimension of the wiring portion 163 in the Z-axis direction is smaller than the dimension of the terminal portion 162 in the Z-axis direction. The terminal portion 162 is bent approximately 90° relative to the wiring portion 163.

[0059] The basic structure of frame 170 is the same as that of frame 160. Specifically, frame 170 has: a main body portion 171 disposed at a position separating from dielectric block 121 in the negative Y-axis direction; and a protrusion 174 protruding from the main body portion 171 toward dielectric block 121 in the positive Y-axis direction. Protrusion 174 includes: a terminal portion 172 disposed at the top of protrusion 174, having a surface abutting against the side surface 121a of dielectric block 121; and a wiring portion 173 disposed between the main body portion 171 and the terminal portion 172. The surface of terminal portion 172 that abuts against the side surface 121a (hereinafter also simply referred to as the "abutting surface of terminal portion 172") extends in the positive Z-axis direction and faces the side surface 121a of dielectric block 121. The dimension of wiring portion 173 in the Z-axis direction is smaller than the dimension of terminal portion 172 in the Z-axis direction. Terminal portion 172 is bent approximately 90° relative to wiring portion 173.

[0060] The basic structure of frame 180 is the same as that of frame 160. Specifically, frame 180 has: a main body portion 181 disposed at a position separating from dielectric block 121 in the positive X-axis direction; and a protrusion 184 protruding from the main body portion 181 toward dielectric block 121 in the negative X-axis direction. Protrusion 184 includes: a terminal portion 182 disposed at the top of protrusion 184, having a surface abutting against the side surface 121a of dielectric block 121; and a wiring portion 183 disposed between the main body portion 181 and the terminal portion 182. The surface of terminal portion 182 that abuts against the side surface 121a (hereinafter also simply referred to as the "abutting surface of terminal portion 182") extends in the positive Z-axis direction and faces the side surface 121a of dielectric block 121. The dimension of wiring portion 183 in the Z-axis direction is smaller than the dimension of terminal portion 182 in the Z-axis direction. Terminal portion 182 is bent approximately 90° relative to wiring portion 183.

[0061] The main body portions 151, 161, 171, and 181 are arranged at different positions surrounding the dielectric block 121 when viewed from the Z-axis direction. Specifically, the main body portions 151, 161, 171, and 181 are respectively arranged in the normal direction of the four sides forming the side surface 121a of the dielectric block 121.

[0062] Terminal portions 152, 162, 172, and 182 respectively abut against the four sides of the side surface 121a forming the dielectric block 121. In other words, when the region of the dielectric block 121 viewed from the Z-axis direction is divided into two by a dividing line corresponding to the XZ plane passing through the center of the top surface of the dielectric block 121, terminal portions 152 and 172 are arranged in different regions. Similarly, when the region of the dielectric block 121 viewed from the Z-axis direction is divided into two by a dividing line corresponding to the YZ plane passing through the center of the top surface of the dielectric block 121, terminal portions 162 and 182 are arranged in different regions.

[0063] The wiring portion 153 of frame 150 extends in a straight line along the normal direction (Y-axis direction) of the contact surface of terminal portion 152. The wiring portion 163 of frame 160 extends in a straight line along the normal direction (X-axis direction) of the contact surface of terminal portion 162. The wiring portion 173 of frame 170 extends in a straight line along the normal direction (Y-axis direction) of the contact surface of terminal portion 172. The wiring portion 183 of frame 180 extends in a straight line along the normal direction (X-axis direction) of the contact surface of terminal portion 182.

[0064] As described above, in the antenna device 120 of this embodiment, the mounting surface 130a of the substrate 130 includes a cuboid-shaped dielectric block 121 and a flat metal frame 150. The frame 150 has: a main body portion 151, which is disposed at a position separate from the dielectric block 121; a wiring portion 153, which extends from the main body portion 151 toward the dielectric block 121; a terminal portion 152, which is disposed at the top end of the wiring portion 153; and a branch portion 155, which branches off from the wiring portion 153 and is connected to the power supply point SP (power supply wiring 140).

[0065] The terminal portion 152 of the frame 150 has an abutment surface that extends along the Z-axis and abuts against the side surface 121a of the dielectric block 121. Therefore, compared to, for example, the case where a thin wire abuts against the side surface 121a of the dielectric block 121, the dielectric block 121 can be supported more strongly, making it difficult for the dielectric block 121 to displace towards the frame 150.

[0066] The branch 155 of the frame 150 is connected to the power supply point SP (power supply wiring 140). Therefore, the high-frequency signal from the power supply point SP can be supplied to the side 121a of the dielectric block 121 via the branch 155 of the frame 150, a portion of the wiring portion 153 and the terminal portion 152.

[0067] By setting up a frame 150 with such a structure, it is possible to supply power to the dielectric block 121 and support the dielectric block 121.

[0068] Furthermore, the mounting surface 130a of the substrate 130 includes frames 160, 170, and 180. These frames 160, 170, and 180 respectively have main body portions 161, 171, and 181, wiring portions 163, 173, and 183, and terminal portions 162, 172, and 182.

[0069] The terminal portion 152 of frame 150 and the terminal portions 162, 172, and 182 of frames 160, 170, and 180 have positions different from each other relative to the side surface 121a of dielectric block 121. Specifically, they form abutment surfaces that abut against each of the four sides of side surface 121a. Through these frames 150, 160, 170, and 180, dielectric block 121 can be held in a manner that prevents displacement along the mounting surface 130a.

[0070] Furthermore, the main body portions 151, 161, 171, and 181 are arranged to surround the dielectric block 121 when viewed from above along the Z-axis. Moreover, the wiring portions 153, 163, 173, and 183 extend linearly along the normal direction of the contact surfaces of the terminal portions 152, 162, 172, and 182, respectively. This allows for a significant reduction in the length of the wiring portions 153, 163, 173, and 183, suppressing antenna characteristic degradation caused by the generation of unwanted modes. In other words, if the wiring portions 153, 163, 173, and 183 become longer, there may be a corresponding problem of unwanted modes being generated, leading to antenna characteristic degradation as a dielectric resonator antenna; however, in the antenna device 120 of this embodiment, such a problem can be suppressed.

[0071] Furthermore, when the dielectric block 121 is divided into two by an XZ plane passing through the center of its top surface, terminal portions 152 and 172 are arranged in different regions, sandwiching the dielectric block 121. Similarly, when the dielectric block 121 is divided into two by a YZ plane passing through the center of its top surface, terminal portions 162 and 182 are arranged in different regions, sandwiching the dielectric block 121. This improves the holding force of the frames 150, 160, 170, and 180 on the dielectric block 121.

[0072] Furthermore, the wiring portion 153 of the frame 150 is connected to the dielectric block 121 at one end and to the main body portion 151 connected to the ground electrode GND at the other end. Also, the branch portion 155 of the frame 150 branches off from a point on the wiring portion 153 that is closer to the terminal portion 152 than to the connection portion connected to the main body portion 151. In other words, the wiring portion 153 of the frame 150 is connected to the power supply point SP (power supply wiring 140) at a point closer to the terminal portion 152 than to the connection portion connected to the main body portion 151. With this structure, the wiring portion 153 connected to the power supply point SP (power supply wiring 140) can function as a short-circuit stub for matching adjustment. By performing matching adjustment, the antenna gain can be improved.

[0073] Furthermore, in the antenna device 120 of this embodiment, the main body portions 151, 161, 171, and 181 of the frames 150, 160, 170, and 180 are divided into smaller portions and arranged on the mounting surface 130a. As a result, the area occupied by the main body portions 151, 161, 171, and 181 on the mounting surface 130a can be reduced, and other components, wiring, matching circuits, etc., can be arranged in the freed-up space.

[0074] Furthermore, in the antenna device 120 of this embodiment, the terminal portions 152, 162, 172, and 182 are bent relative to the wiring portions 153, 163, 173, and 183, respectively, and abut against the side surface 121a of the dielectric block 121. Therefore, the terminal portions 152, 162, 172, and 182 of the dielectric block 121 are firmly supported by the wiring portions 153, 163, 173, and 183 and the main body portions 151, 161, 171, and 181. As a result, compared to the case where the terminal portions 152, 162, 172, and 182 are individually arranged without being connected to the wiring portions 153, 163, 173, and 183 and the main body portions 151, 161, 171, and 181, the holding force of the dielectric block 121 can be further strengthened.

[0080] <Variation Example 1>

[0081] In the above embodiments, the main body portions 151, 161, 171, and 181 are divided, but they can also be formed integrally.

[0082] Figure 4 The figure is obtained by magnifying the periphery of a dielectric block 121 of the antenna device 120A of this modified example 1.

[0083] The antenna device 120A of this variation is obtained by replacing the four frames 150, 160, 170, and 180 of the antenna device 120 of the above-described embodiment with a single frame 150A. The frame 150A is obtained by replacing the main body portions 151, 161, 171, and 181 of the antenna device 120 of the above-described embodiment with an integrally formed main body portion 151A. The main body portion 151A, when viewed from the Z-axis direction, is arranged to surround the entire periphery of the dielectric block 121. The protrusions 154, 164, 174, and 184 of the frame 150A protrude from the integrally formed main body portion 151A toward the dielectric block 121.

[0084] In this way, by adopting a frame 150A with an integrated main body 151A, the manufacturing and configuration processes of the frame 150A can be simplified compared to the case of a split main body.

[0085] The "main body 151A" of this modified example 1 can correspond to the structure in which the "first main body" and "second main body" of this disclosure are integrally formed.

[0086] <Variation Example 2>

[0087] In the above embodiments, the dielectric block 121 is placed on the mounting surface 130a of the substrate 130, but the dielectric block 121 can also be embedded in the recess of the substrate 130.

[0088] Figure 5 The figure is obtained by magnifying the periphery of a dielectric block 121 of the antenna device 120B of this modified example 2. Figure 6 It means from Figure 5 The diagram shows the state of the antenna device 120B with the dielectric block 121 removed.

[0089] The antenna device 120B of this Modification Example 2 is obtained by replacing the substrate 130 and frame 150A of the antenna device 120A of Modification Example 1 with substrate 130B and frame 150B, respectively. The frame 150B is obtained by replacing the protrusions 154, 164, 174, and 184 of the frame 150A of Modification Example 1 with protrusions 154B, 164B, 174B, and 184B, respectively.

[0090] A recess 131 is formed near the center of the mounting surface 130b of the substrate 130B, recessed in the negative Z-axis direction. When the substrate 130B is viewed from above in the Z-axis direction, the ground electrode GND has a portion disposed at a position overlapping with the recess 131. Alternatively, the recess 131 may be a hole through the substrate 130B containing the ground electrode GND.

[0091] The lower part of the dielectric block 121 is embedded in the recess 131 of the substrate 130B.

[0092] The protrusion 154B has a wiring portion 153 and a terminal portion 152B. The terminal portion 152B is bent at approximately 90° relative to the wiring portion 153 along the inner wall 131b of the recess 131. Similarly, the terminal portions 162B of the protrusion 164B, 172B of the protrusion 174B, and 182B of the protrusion 184B are also bent at approximately 90° relative to the wiring portions 163, 173, and 183 respectively along the inner wall of the recess 131. Therefore, with the lower part of the dielectric block 121 embedded in the recess 131 of the substrate 130B, the terminal portions 152B, 162B, 172B, and 182B are disposed between the inner wall of the recess 131 and the side surface 121a of the dielectric block 121.

[0093] In the antenna device 120B of this modified example 2, the dielectric block 121 is embedded in the recess 131 of the substrate 130, so the height of the dielectric block 121 from the mounting surface 130b can be suppressed to a low level, and the dielectric block 121 can be held by the inner wall of the recess 131, thus improving the holding force of the dielectric block 121.

[0094] Furthermore, in the antenna device 120B of this modified example, when the substrate 130B is viewed from above in the Z-axis direction, the ground electrode GND is positioned overlapping the recess 131. Therefore, the lower surface of the dielectric block 121 can be positioned opposite the ground electrode GND. As a result, the antenna characteristics as a dielectric resonator antenna can be improved.

[0095] In this modified example 2, "recess 131" and "inner wall 131b of recess 131" can respectively correspond to "recess" and "inner wall of recess" in this disclosure.

[0096] <Variation Example 3>

[0097] Alternatively, at least one of the terminal portions 152B, 162B, 172B, and 182B in the above-described modified example 2 can be modified into a shape that can elastically deform in the normal direction of the side surface 121a of the abutting dielectric block 121.

[0098] Figure 7 This is a cross-sectional view of the antenna device 120C in this modified example 3, cut along the YZ plane. For example... Figure 7 As shown, in this modified example 3, the terminal portions 152C and 172C extend along the Z-axis direction in a serrated bend. Therefore, the terminal portions 152C and 172C can elastically deform in the normal direction (Y-axis direction) of the side surface 121a of the contacting dielectric block 121. Thus, the elastic deformation of the terminal portions 152C and 172C in the Y-axis direction can absorb deviations in the forming accuracy of the recess 131 of the substrate 130. As a result, the holding force of the dielectric block 121 can be improved.

[0099] In this modified example 3, "terminal portion 152C" and "terminal portion 172C" can respectively correspond to "first terminal portion" and "second terminal portion" of this disclosure.

[0100] <Variation Example 4>

[0101] In the above-described variation 1, each terminal portion 152, 162, 172, and 182 is bent relative to the wiring portions 153, 163, 173, and 183, respectively, and abuts against the side surface 121a of the dielectric block 121. However, the thickness (dimension in the Z-axis direction) of each wiring portion can be increased to the height (dimension in the Z-axis direction) of each terminal portion, so that the top surface of each terminal portion abuts against the side surface 121a of the dielectric block 121.

[0102] Figure 8 This is a magnified view of the periphery of a dielectric block 121 of the antenna device 120D in this modified example 4. The antenna device 120D is obtained by changing the frame 150A of the antenna device 120A in the modified example 1 above to the frame 150D.

[0103] The frame 150D is obtained by increasing the thickness (dimension in the Z-axis direction) of the main body 151A and wiring portions 153, 163, 173, 183 of the frame 150A in the above-described modified example 1 to the height (dimension in the Z-axis direction) of the terminal portions 152, 162, 172, 182 of the frame 150A.

[0104] Specifically, the frame 150D has a main body 151D and protrusions 154D, 164D, 174D, and 184D. The height (dimension in the Z-axis direction) of the main body 151D and the protrusions 154D, 164D, 174D, and 184D is approximately equal.

[0105] The protrusion 154D has a terminal portion 152D, a wiring portion 153D, and a branch portion 155D. The height (dimension in the Z-axis direction) of the wiring portion 153D is greater than the width (dimension in the X-axis direction) of the wiring portion 153D, and is approximately equal to the height (dimension in the Z-axis direction) of the terminal portion 152D. That is, the terminal portion 152D is the top surface of the wiring portion 153D.

[0106] The protrusion 164D has a terminal portion 162D and a wiring portion 163D. The height (dimension in the Z-axis direction) of the wiring portion 163D is greater than the width (dimension in the Y-axis direction) of the wiring portion 163D, and is approximately equal to the height (dimension in the Z-axis direction) of the terminal portion 162D. That is, the terminal portion 162D is the top surface of the wiring portion 163D.

[0107] Similarly, the protrusion 174D has a terminal portion 172D and a wiring portion 173D. The height (dimension in the Z-axis direction) of the wiring portion 173D is greater than the width (dimension in the X-axis direction) of the wiring portion 173D, and is approximately equal to the height (dimension in the Z-axis direction) of the terminal portion 172D. That is, the terminal portion 172D is the top surface of the wiring portion 173D.

[0108] Similarly, the protrusion 184D has a terminal portion 182D and a wiring portion 183D. The height (dimension in the Z-axis direction) of the wiring portion 183D is greater than the width (dimension in the Y-axis direction) of the wiring portion 183D, and is approximately equal to the height (dimension in the Z-axis direction) of the terminal portion 182D. That is, the terminal portion 182D is the top surface of the wiring portion 183D.

[0109] As described above, the thickness (dimension in the Z-axis direction) of each wiring portion 153D, 163D, 173D, and 183D can be increased so that the top surface of each wiring portion 153D, 163D, 173D, and 183D abuts against the side surface 121a of the dielectric block 121.

[0110] In this way, the stability of the orientation of dielectric block 121 is improved, which in turn makes the antenna characteristics as a dielectric resonator antenna stable.

[0111] In this variation 4, the "top surface of wiring section 153D" and the "top surfaces of wiring sections 163D, 173D, and 183D" can respectively correspond to the "top surface of the first wiring section" and the "top surface of the second wiring section" of this disclosure.

[0112] <Variation Example 5>

[0113] In the above-described embodiments and variations 1 to 4, the dielectric block 121 is held by four protrusions, but the number of protrusions holding the dielectric block 121 may be five or more.

[0114] Figure 9 This is a magnified view of the periphery of a dielectric block 121 of the antenna device 120E in this modified example 5. The antenna device 120E is obtained by changing the frame 150D of the antenna device 120D in the modified example 4 to the frame 150E.

[0115] Frame 150E is a frame obtained by adding protrusions 210 and 220 to frame 150D of the above-described variation 4. Each of the protrusions 210 and 220 has the same height (Z-axis dimension) as the main body 151D, and protrudes from the main body 151D toward the dielectric block 121, with its top surface abutting against the side surface 121a of the dielectric block 121.

[0116] In the antenna device 120E of this modified example 5, a total of six protrusions 154D, 164D, 174D, 184D, 210, and 220 are used to hold the dielectric block 121. As a result, the stability of the orientation of the dielectric block 121 is improved, and the antenna characteristics as a dielectric resonator antenna can be stabilized.

[0117] <Variation Example 6>

[0118] In the above-described embodiments and variations 1 to 5, the height of the wiring portion of the power supply protrusion connected to the power supply point SP is approximately equal to the height of the wiring portion of the other holding protrusions, but it is also possible for the height of the wiring portion of the power supply protrusion to be different from the height of the wiring portion of the holding protrusion.

[0119] Figure 10 The figure is a partial magnification of the periphery of a dielectric block 121 of an antenna device 120F of this modified example 6. The frame 160F of the antenna device 120F has a power supply protrusion 154 and holding protrusions 164D, 174D, 184D, 210, 220, 230, and 240.

[0120] The power supply protrusion 154, like the frame 150 in the above embodiment, has a thin plate shape, with its top end bent at approximately 90° relative to the wiring portion and abutting against the side surface 121a of the dielectric block 121. In contrast, the holding protrusions 164D, 174D, 184D, 210, 220, 230, and 240 are higher than the wiring portion of the power supply protrusion 154, and their top surfaces abut against the side surface 121a of the dielectric block 121.

[0121] Figure 11 This is a magnified view of the periphery of a dielectric block 121 of the antenna device 120G, another example of this modified example 6. The frame 160G of the antenna device 120G is derived from the above-described... Figure 10 The frame 160F of the antenna device 120F is obtained by removing the holding protrusions 164D, 174D, 184D, 230, and 240. That is, the frame 160G includes a power supply protrusion 154 with a thin plate shape and holding protrusions 210 and 220 that are thicker than the power supply protrusion 154.

[0122] As described above, the wiring portion of the power supply protrusion 154 can be made thinner and the wiring portion of the holding protrusion can be made thicker. Thus, by changing the length and width of the wiring portion of the power supply protrusion 154, the electrical characteristics can be finely adjusted and the dielectric block 121 can be firmly held by the holding protrusion.

[0123] <Variation Example 7>

[0124] Figure 12 The figure is obtained by magnifying the periphery of a dielectric block 121 of the antenna device 120H in this modified example 7.

[0125] Antenna device 120H is an antenna device obtained by adding a first electrode pattern 156 and second electrode patterns 166, 176, and 186 to the antenna device 120 of the above embodiment.

[0126] The first electrode pattern 156 is disposed between the power supply protrusion 154 and the mounting surface 130a of the substrate in a state of contact with the protrusion 154, and is connected to the power supply point SP. When viewed from above in the Z-axis direction, the first electrode pattern 156 is disposed along the power supply protrusion 154 at a position overlapping with the power supply protrusion 154.

[0127] By configuring the first electrode pattern 156 in this way, even if the distance between the power supply protrusion 154 and the ground electrode GND disposed on the lower layer of the substrate 130 deviates due to manufacturing deviations, no electrical influence will occur. As a result, the electrical characteristics of the power supply protrusion 154 can be stabilized.

[0128] The second electrode patterns 166, 176, and 186 are respectively disposed between the retaining protrusions 164, 174, and 184 and the mounting surface 130a of the substrate, in contact with the protrusions 164, 174, and 184. When viewed from above in the Z-axis direction, the second electrode patterns 166, 176, and 186 are disposed at positions overlapping with the retaining protrusions 164, 174, and 184, respectively.

[0129] Figure 13 This is a cross-sectional view of the antenna device 120H when it is cut through the YZ plane of the second electrode pattern 176. (See image below.) Figure 13 As shown, the second electrode pattern 176 is connected to the ground electrode GND disposed on the lower layer of the substrate 130 via the passage 177. In addition, although not shown, the other second electrode patterns 166 and 186 are also connected to the ground electrode GND disposed on the lower layer of the substrate 130 via the same passage as the second electrode pattern 176.

[0130] By configuring such second electrode patterns 166, 176, and 186, unwanted waves from the retaining protrusions 164, 174, and 184 can be suppressed.

[0131] The “first electrode pattern 156” and “second electrode patterns 166, 176, 186” in this variation 7 can correspond to the “first electrode pattern” and “second electrode pattern” of this disclosure, respectively.

[0132] <Variation Example 8>

[0133] In the antenna device 120 of the above-described embodiment, the main body portions 151, 161, 171, and 181 of the frame are arranged to surround the dielectric block 121, but the main body portions of the frame are not necessarily limited to being arranged to surround the dielectric block 121.

[0134] Figure 14 This is a perspective view of an antenna device 120I, one of the variations of this example 8. In the antenna device 120I, a main body portion is provided with a frame on each side in the X-axis direction, clamping the dielectric block.

[0135] Figure 15 This is a perspective view of antenna device 120J, another example of this variation 8. In antenna device 120J, a main body of a frame is arranged on both sides of a dielectric block 121 in the Y-axis direction.

[0136] In this way, the main body of the frame can also be configured by clamping the dielectric block 121.

[0137] <Variation Example 9>

[0138] In the above-described embodiments and variations 1 to 8, there is one protrusion for power supply provided for a dielectric block, but the number of protrusions for power supply provided for a dielectric block may be two or more.

[0139] Figure 16This is a magnified view of the periphery of a dielectric block 121 of an antenna device 120K in one of the modified examples of this embodiment 9. The antenna device 120K is an antenna device obtained by changing the frame 160 of the antenna device 120 in the above-described embodiment to a frame 160K.

[0140] Like frame 150, frame 160K has a power supply protrusion but not a retention protrusion. Specifically, frame 160K has: a main body portion positioned apart from dielectric block 121 in the negative X-axis direction; and a protrusion extending from the main body portion toward dielectric block 121 in the positive X-axis direction. The protrusion of frame 160K has the same structure as the protrusion of frame 150 and is connected to power supply point SP2.

[0141] In antenna device 120K, high-frequency signals from the protrusions of frame 150 and from the protrusions of frame 160K can be supplied to each dielectric block 121. The polarization direction of the radiated radio waves differs depending on the supply location of the high-frequency signals to the dielectric blocks 121. That is, antenna device 120K is a so-called dual-polarized antenna module capable of radiating radio waves in two different polarization directions.

[0142] Figure 17 This is a magnified view of the periphery of a dielectric block 121 of the antenna device 120L in another example of this modified example 9. The antenna device 120L is an antenna device obtained by changing the frame 170 of the antenna device 120 in the above-described embodiment to a frame 170L.

[0143] Like frame 150, frame 170L has a power supply protrusion but not a retention protrusion. Specifically, frame 170L has: a main body portion positioned apart from dielectric block 121 in the negative Y-axis direction; and a protrusion extending from the main body portion toward dielectric block 121 in the positive Y-axis direction. The protrusion of frame 170L has the same structure as the protrusion of frame 150 and is connected to power supply point SP3.

[0144] In the antenna device 120L, high-frequency signals from the protrusions of the frame 150 and from the protrusions of the frame 170L can be supplied to each dielectric block 121. For example, by adjusting the phase difference between the high-frequency signals from the protrusions of the frame 150 and the high-frequency signals from the protrusions of the frame 170L, the characteristics of the radio waves radiated from each dielectric block 121 can be adjusted.
