Currently, antennas can be strategically placed within communication devices to facilitate the reception and transmission of signals, thereby enabling communication. However, an examination of existing products shows that most antennas are limited to radiating in a single direction when fixed within the communication device. In addition, the peak gain of these antennas is considerably limited. Therefore, there is still a distinct lack of viable solutions aimed at improving the performance of these antennas. This highlights the urgent need for innovative strategies to address this prevalent problem. Summary of the invention

[0022] In the following context, when it is mentioned that A is substantially equal to B, it means that the difference between A and B is less than 5% of A or B.
[0023] Figure 1 An antenna arrangement 100 according to one embodiment is shown. Figure 2 Shown Figure 1 An exploded perspective view of the antenna device 100 in FIG. Figure 2, the antenna 110 and the support member 120 are separated for ease of explanation and understanding. The antenna device 100 may include one antenna 110 and one support member 120. The antenna 110 may radiate electromagnetic waves W for wireless communication.
[0024] The antenna 110 may include a conductive plate 112, a circuit 116, and a connector 118. The conductive plate 112 may be formed using a metal layer and used to radiate electromagnetic waves W. The conductive plate 112 may be fixed with a dielectric layer 1121 and exposed to radiate electromagnetic waves W. The circuit 116 may be disposed in a molding compound layer and connected to the conductive plate 112. The circuit 116 may process a signal corresponding to the electromagnetic wave W. The circuit 116 may include a radio-frequency integrated circuit (RFIC), a power management integrated circuit (PMIC), a resistor, an inductor, and / or a capacitor. The connector 118 may be coupled to the circuit 116 to transmit a signal to an external circuit, such as an external processor.
[0025] The support member 120 can accommodate, support and fix the antenna 110. The support member 120 can be fixed inside the communication device (e.g., mobile phone) by screws, latches, fasteners, welding and / or adhesives to install the antenna 110 in the communication device. The part of the communication device that may block the electromagnetic waves radiated by the antenna 110 should be made of non-metallic materials, such as plastic.
[0026] The support member 120 may be made of a material having sufficient hardness and electrical conductivity, such as metal or other suitable materials. The support member 120 may have a storage space in which the antenna 110 is placed. The support member 120 may have a first hole A1 facing a first direction D1, and a second hole A2 facing a second direction D2 different from the first direction D1.
[0027] The antenna 110 placed in the support member 120 may radiate electromagnetic waves W in a first direction D1 through the first hole A1 and radiate electromagnetic waves W in a second direction D2 through the second hole A2.
[0028] like Figure 2 As shown, the support member 120 may further have a third hole A3 facing a third direction D3 different from the first direction D1 and the second direction D2. The antenna 110 may also radiate electromagnetic waves W in the third direction D3 through the third hole A3.
[0029] Therefore, the first direction D1, the second direction D2, and the third direction D3 may be the radiation directions of the antenna device 100. As a result, the antenna device 100 may have a plurality of radiation directions to improve the radiation pattern and the communication performance. By adjusting the structure of the support member 120, the positions of the first hole A1, the second hole A2, and the third hole A3 may be adjusted, thereby adjusting the first direction D1, the second direction D2, and the third direction D3.
[0030] The second direction D2 may be substantially perpendicular to the first direction D1. The third direction D3 may be substantially perpendicular to the first direction D1 and opposite to the second direction D2.

The antenna 110 may be placed between the first conductive sheet 122 and the second conductive sheet 124. The first hole A1 may be formed on the first conductive sheet 122.
[0032] The first conductive sheet 122 may include a first conductive portion P1 between a first edge 1221 of the first conductive sheet 122 and a first side S1 of the antenna 110 , and the second conductive sheet 124 may include a second conductive portion P2 between a first edge 1241 of the second conductive sheet 124 and the first side S1 of the antenna 110 .
[0033] The first conductive portion P1 may have a width W1, and the second conductive portion P2 may have a width W2.
[0034] The first conductive portion P1 and the second conductive portion P2 may guide the propagation of the electromagnetic wave W to enhance the gain of the antenna 110. The width W1 and the width W2 may be greater than a predetermined length. For example, the predetermined length may be 0.03 times the wavelength of the electromagnetic wave W radiated by the antenna 110 to increase the antenna gain by at least 2.5 dB or at least 3.0 dB.
[0035] In some embodiments, the first conductive portion P1 and the second conductive portion P2 may have different widths. Figure 3 , the width W1 may be different from the width W2 (ie, W1≠W2).
[0036] In other embodiments, the first conductive portion P1 and the second conductive portion P2 may have the same width. Figure 3 , the width W1 may be substantially equal to the width W2 (ie, W1 = W2).
[0037] The first conductive sheet 122 may further have a third conductive portion P3 between the second edge 1222 of the first conductive sheet 122 and the second side S2 of the antenna 110. The first side S1 and the second side S2 of the antenna 110 may be parallel. The third conductive portion P3 may have a width W3. The first conductive portion P1 and the third conductive portion P3 may have different widths (i.e., W1≠W3). In other embodiments, the first conductive portion P1 and the third conductive portion P3 may have the same width (i.e., W1=W3).
[0038] The second conductive sheet 124 may further have a fourth conductive portion P4 between the second edge 1242 of the second conductive sheet 124 and the second side S2 of the antenna 110. The fourth conductive portion P4 may have a width W4. The second conductive portion P2 and the fourth conductive portion P4 may have different widths (i.e., W2≠W4). In other embodiments, the second conductive portion P2 and the fourth conductive portion P4 may have the same width (i.e., W2=W4).
[0039] Regarding the widths of the third conductive portion P3 and the fourth conductive portion P4, the third conductive portion P3 and the fourth conductive portion P4 may have different widths (ie, W3≠W4), or the third conductive portion P3 and the fourth conductive portion P4 may have the same width (ie, W3=W4). Various combinations of widths W1 to W4 are within the scope of the embodiment.
[0040] like Figure 3 As shown, at least one of the first conductive portion P1 and the second conductive portion P2 may form a right angle (eg, angle θ1) with the first side S1 of the antenna 110. At least one of the third conductive portion P3 and the fourth conductive portion P4 may form a right angle with the second side S2 of the antenna 110.
[0041] Figure 4 According to another embodiment, Figure 1 At least one of the first conductive portion P1 and the second conductive portion P2 may not be perpendicular to the first side S1 of the antenna 110. Figure 4 As shown, the first portion P1 and the first side S1 of the antenna 110 may form an acute angle θ41, and the second portion P2 and the first side S1 of the antenna 110 may form an obtuse angle θ42. At least one of the third conductive portion P3 and the fourth conductive portion P4 may not be perpendicular to the second side S2 of the antenna 110.

[0043] By adjusting the widths and shapes of the first conductive portion P1 , the second conductive portion P2 , the third conductive portion P3 , and the fourth conductive portion P4 , the direction and effect of guiding the electromagnetic wave W may be optimized, thereby improving the gain of the antenna 110 .
[0044] Figure 6 An antenna arrangement 600 according to another embodiment is shown. Figure 1 , Figure 2 and Figure 6 The similarities will not be repeated. The antenna device 600 may further have a fourth hole A4 facing the first direction D1 and formed on the first conductive sheet 122. The first conductive sheet 122 may include a reinforcing rod 128 for separating the first hole A1 and the fourth hole A4 and reinforcing the structure of the support member 120. Figure 1 and Figure 6 , Figure 1 The support member 120 in the embodiment may have a larger first hole A1 without the reinforcing rod 128, and therefore, when the communication device accommodating the antenna device 600 is impacted, the support member 120 may be easily deformed or damaged. Figure 6 In the embodiment, the support member 120 may have smaller holes (eg, A1 and A4) facing the first direction D1 to replace Figure 1 The larger first hole A1 in the Figure 6 With the reinforcing rod 128, the supporting component 120 can exhibit higher impact resistance and reliability. Figure 6 The functions of the first hole A1 and the fourth hole A4 in the Figure 1 The first hole A1 in. Figure 6 The antenna 110 in the embodiment can radiate electromagnetic waves W in the first direction D1 through the first hole A1 and the fourth hole A4. The reinforcing rod 128 should not hinder the conductive plate 112 of the antenna 110 to avoid affecting the radiation of the electromagnetic waves W. If the size of the antenna 110 is small, or the structure of the antenna 100 is strong enough, the reinforcing rod 128 is not required and can be used. Figure 1 When the size of the antenna 110 is large, a reinforcing rod 128 may be used to develop Figure 6 The structure shown.

A first hole A1 may be formed on the first conductive component 810, and a second hole A2 may be formed between the first conductive component 810 and the second conductive component 820.

[0047] like Figure 7 and Figure 8 As shown, the normal line N1 of the fixing portion 129 may be aligned with the first direction D1 , and thus the screw 720 may pass through the hole H1 in a direction parallel to the normal line N1 .
[0048] exist Figure 7 and Figure 8 In the embodiment, the fixing portion 129 is formed with the second conductive component 820 corresponding to the circuit 116.

For example, the external board 988 may be a printed circuit board (PCB), an inner wall, or a suitable board in a mobile phone. The antenna device 900 may include an antenna 110 and a support member 120. The support member 120 may be formed by a conductive component 910 provided corresponding to the conductive plate 112 of the antenna 110. The conductive component 910 may include a conductive sheet 922 and two side walls 924 and 926 connected to the conductive sheet 922. A first hole A1 may be formed on the conductive sheet 922.

[0050] exist Fig. 9 and Fig.10 , a normal line N91 of the fixing portion 929 may be aligned with the first direction D1, and thus the screw 920 may pass through the hole H91 in a direction parallel to the normal line N91.
[0051] exist Figure 7 and Figure 8 In the embodiment, the screw 720 can be tightened in the first direction D1, and Fig. 9 The screw 920 in the embodiment may be tightened in a direction opposite to the first direction D1. However, the embodiment is not limited thereto.
[0052] Fig.11 An antenna arrangement 1100 according to another embodiment is shown. Fig.12 Shown Fig.11 1 is an exploded perspective view of the antenna device 1100 in FIG. In the antenna device 1100, the support member 120 may include a first conductive component 1110 and a second conductive component 1120. At least one of the first conductive component 1110 and the second conductive component 1120 may include a fixing portion 1129. A normal line N111 of the fixing portion 1129 may be perpendicular to the first direction D1. Therefore, the screw 1165 may pass through the hole H111 in a direction parallel to the normal line N111. For example, the screw 1165 may pass through the hole H111 in the second direction D2 or the third direction D3. Optionally, a heat dissipation pad 1155 may be provided for heat dissipation.

The communication device 1400 may be a mobile phone, a tablet computer, a laptop computer or a portable device. The antenna device 1300 may include an antenna 110 and a support component 120. The support component 120 may include a conductive component 1320. The conductive component 1320 may include a conductive sheet 1324, two side walls 1326 and 1328, and two fixed parts 1327 and 1329. Since the fixed part 1327 is similar to the fixed part 1329, the fixed part 1329 is taken as an example for description below. The fixed part 1329 may have a hole H131, and the normal N131 of the fixed part 1329 may be perpendicular to the first direction D1. The screw 1365 may pass through the hole H131 to fix the antenna device 1300. Optionally, a heat dissipation pad 1355 may be provided for heat dissipation.
[0054] like Fig.14 As shown, the communication device 1400 may include a side wall 1455 of a chassis and two fixing blocks 1422 and 1424.

[0055] When the antenna device radiates electromagnetic waves W in the first direction D1, the second direction D2 and / or the third direction D3, the corresponding parts of the communication device 1400 should be made of non-conductive materials (such as plastic, resin, etc.). This can prevent the radiation of the electromagnetic waves W from being interfered. Fig.14 In the area corresponding to the second aperture A2, the housing may use non-metallic materials (such as plastic) to prevent electromagnetic wave shielding.

Through the positioning elements 1525, the size of the frame portion 1527 may be adjusted to increase the gap G1 around the antenna 1510, thereby enhancing the antenna gain. Figures 1 to 14The antenna device may also include Fig.15 and Fig.16 A positioning element 1525 is provided in the antenna to adjust the gap around the antenna.
[0057] Each antenna device 100, 600, 700, 900, 1100, 1300 and 1500 can be installed inside a communication device, such as a mobile phone, a laptop or a tablet computer. Fig.15 For example, the edge E1 of the antenna device 1500 may be parallel or non-parallel to the edge of the housing of the communication device (eg, mobile phone).
