[0032] Figure 1A cross-sectional view of an antenna system 100 is shown according to an embodiment of the present invention. The antenna system 100 includes a first antenna 110 and a second antenna 120. The first antenna 110 includes a first horizontal portion 115 for accessing a first wireless signal S1. The first wireless signal S1 is transmitted and / or received through the first horizontal portion 115 and a first reference layer 118. The second antenna 120 includes a second horizontal portion 125 for accessing a second wireless signal S2. The second wireless signal S2 is transmitted and / or received through the second horizontal portion 125 and a second reference layer 128 different from the first reference layer 118. The first wireless signal S1 may be located in a first frequency band (also described as a "frequency band"), and the second wireless signal S2 may be located in a second frequency band. Furthermore, the frequencies in the second frequency band are higher than the frequencies in the first frequency band (for ease of understanding and explanation, in embodiments of the present invention, the first frequency band is sometimes described as a "low frequency band" or "lower frequency band," and the second frequency band is described as a "high frequency band" or "higher frequency band"). In other words, the first antenna 110 can access wireless signals in the lower frequency band, while the second antenna 120 can access wireless signals in the higher frequency band. In some embodiments, the ratio of the highest frequency of the higher frequency band to the lowest frequency of the lower frequency band may be greater than 2.

[0033] For example, in 5G millimeter wave (mmWave) communication, the low-frequency band corresponding to the first antenna 110 can be below 30 GHz (e.g., 24 GHz-30 GHz), while the high-frequency band corresponding to the second antenna 120 can be between 30 GHz and 71 GHz.

[0034] The first antenna 110 may further include a first feeding element 116, which is used to access the first transmission signal S10 corresponding to the first wireless signal S1. The second antenna 120 may further include a second feeding element 126, which is used to access the second transmission signal S20 corresponding to the second wireless signal S2.

[0035] exist Figure 1In the example, the first power supply component 116 is connected to the first horizontal section 115, and the second power supply component 126 is connected to the second horizontal section 125, but the embodiments of the present invention are not limited thereto. For example, the first power supply component 116 and the first horizontal section 115 may not be connected (e.g., the first power supply component 116 and the first horizontal section 115 are wirelessly coupled), and the second power supply component 126 and the second horizontal section 125 may also not be connected (e.g., the first power supply component 126 and the first horizontal section 125 are wirelessly coupled), such as... Figure 2 As shown.

[0036] The vertical distance H1 between the first horizontal section 115 and the first reference layer 118 is greater than the vertical distance H2 between the second horizontal section 125 and the second reference layer 128.

[0037] The first reference layer 118 can be a ground layer. The second reference layer 128 can be a reference plane generated by a meta-surface material, meta-material, frequency-selective surface (FSS) material, electromagnetic band gap (EBG) material, artificial impedance surface material, and / or periodic structure. However, the present invention is not limited in this respect; for example, the second reference layer 128 can be a ground layer, and the first reference layer can be a reference plane generated by the materials described above. Lower frequency signals (such as the first wireless signal S1) can pass through the second reference layer 128 for transmission and / or reception, while higher frequency signals are blocked by the second reference layer 128. In other words, the second reference layer 128 has a low-pass characteristic. Therefore, by setting the second reference layer 128, the thickness of the antenna accessing low-frequency signals (e.g., H1) is greater than the thickness of the antenna accessing high-frequency signals (e.g., H2). Therefore, antennas of different frequency bands can be integrated into the same device, for example, into the same substrate or the same circuit board. In the antenna provided in the embodiments of the present invention, the thickness between the radiating component for accessing wireless signals and the reference plane is related to the frequency of the signal to be accessed; for example, the higher the frequency, the smaller the thickness. Therefore, by setting reference planes of different heights for antennas of different frequency bands in the same device, it is possible to integrate antennas of different frequency bands in the same device. In particular, it is possible to integrate high-frequency antennas and low-frequency antennas in the same device.

[0038] exist Figure 1 In this configuration, the first antenna 110 and the second antenna 120 are formed in the same substrate 105. The first antenna 110 and the second antenna 120 may be formed in the antenna layer 106 of the substrate 105. The first transmission signal S10 and the second transmission signal S20 may be transmitted to or received from the circuit layer 108 of the substrate 105. The circuit layer 108 may be formed of multiple conductive layers.

[0039] Figures 2 to 16 Antenna systems of different embodiments are shown. Figures 2 to 16 Zhongyu Figure 1 The similarities will not be elaborated further. Figure 2 A cross-sectional view of an antenna system 200 is shown according to another embodiment of the present invention. In the antenna system 200, a first antenna 110 includes a first feed assembly 116 disconnected from a first horizontal section 115, the first feed assembly 116 being used to access a first transmitted signal S10 corresponding to a first wireless signal S1. Between the first feed assembly 116 and the first horizontal section 115, the signal is transmitted and / or received via wireless couplings. A second antenna 120 includes a second feed assembly 126 disconnected from a second horizontal section 125, the second feed assembly 126 being used to access a second transmitted signal S20 corresponding to a second wireless signal S2. Between the second feed assembly 126 and the second horizontal section 115, the signal is transmitted and / or received via wireless couplings.

[0040] Figure 3 A cross-sectional view of an antenna system 300 is shown according to another embodiment of the present invention. The second reference layer 128 has an opening 310 (e.g., ...). Figure 3 As shown, the notch 310 is located in the region below the horizontal portion 125 of the second antenna 120, for adjusting the second frequency band of the second antenna 120, and also allows the second feed assembly 126 to pass through. For example, the notch 310 allows a portion of the energy of the second wireless signal S2 to be referenced to the first reference layer, thereby increasing the bandwidth of the second frequency band. Figure 3 In this example, the feed components (e.g., 116 and 126) are disconnected from the radiating portion of the antenna (e.g., 115 and 125); however, this is merely an example. For similar... Figure 1 The antenna system of the antenna system 100 in the middle, the second reference layer 128 may also have a notch to adjust the second frequency band.

[0041] Figure 4A cross-sectional view of an antenna system 400 is shown according to another embodiment of the present invention. Similarly, the second reference layer 128 may have an annular opening 410 (e.g., Figure 4 As shown, the annular notch 410 is located in the area below the horizontal portion 125 of the second antenna 120 to adjust the second frequency band of the second antenna 120. In the top view, the annular notch 410 for adjusting the second frequency band can be circular, rectangular, square, or other regular or irregular shapes. Optionally, a columnar element 417 can be used to support the encircled portion 415 of the annular notch 410. Figure 4 In this example, the feed components (e.g., 116 and 126) are not connected (i.e., separate) from the radiating portions of the antenna (e.g., 115 and 125); however, this is merely an example. For similar... Figure 1 The antenna system of antenna system 100 in the middle, the second reference layer 128 may also have a ring notch to adjust the second frequency band.

[0042] Figure 5 A cross-sectional view of an antenna system 500 is shown according to another embodiment of the present invention. The antenna system 500 may further include an electromagnetic bandgap layer 510 for reducing unwanted surface waves W1 and W2. For example, the electromagnetic bandgap layer may be formed by periodically arranged metal blocks (such as...) in corresponding regions of a substrate. Figure 5 The surface waves W1 and W2 (as shown in the small squares) are formed, but this embodiment of the invention does not limit this. Surface waves W1 and W2 will interrupt the radiation of the antenna system 500, and the performance of the antenna system 500 can be improved by reducing surface waves W1 and W2. The electromagnetic bandgap layer 510 may be disposed between the second horizontal portion 125 and the second reference layer 128, but the region 515 directly below the second horizontal portion 125 and between the second reference layer 128 (which can also be described as "the electromagnetic bandgap layer 510 has a cavity / pore 515, that is, the region 515 is not provided with an electromagnetic bandgap layer") is reserved. That is to say, the region 515 (i.e., the cavity / pore 515 of the electromagnetic bandgap layer 510) is not filled / provided with the electromagnetic bandgap layer 510 to transmit the second wireless signal S2.

[0043] Figure 6 A cross-sectional view of an antenna system 600 is shown according to another embodiment of the present invention. The antenna system 600 is similar to the antenna system 500. The antenna system 600 may have an electromagnetic bandgap layer 610. The electromagnetic bandgap layer 610 is used to reduce surface waves W1 and W2, and the electromagnetic bandgap layer 610 is disposed below the first horizontal portion 115 and the second horizontal portion 125 and above the second reference layer 128. In other words, compared to Figure 5 The electromagnetic bandgap layer 510 extends below the first horizontal portion 115. For example... Figure 6 As shown, the electromagnetic bandgap layer 610 is also located below the first horizontal portion 115 (that is, the electromagnetic bandgap layer 610 does not have a cavity / pore below the first horizontal portion 115), because lower frequency signals can pass through the electromagnetic bandgap layer.

[0044] exist Figures 1 to 6 In this embodiment, the first horizontal portion 115 and / or the second horizontal portion 125 may be a patch, but the embodiments of the present invention are not limited thereto.

[0045] Figure 7 A cross-sectional view of an antenna system 700 is shown according to another embodiment of the present invention. Figure 8 A top view of an antenna system 700 is shown. In the antenna system 700, a first horizontal portion 115 may have at least one aperture (also described as a "notch," "aperture," "diameter," etc.) 710. A second horizontal portion 125 may be disposed within the aperture 710. Figure 7 and Figure 8 In the example, the first horizontal portion 115 is shown having four apertures 710, and four second horizontal portions 125 are respectively disposed in the four apertures 710. Therefore, a plurality of second horizontal portions 125 may be disposed within the boundaries of the first horizontal portion 115, as can be understood, as... Figure 8 As shown, the second horizontal section 125 of the second antenna and the first horizontal section 115 of the first antenna are separated by a gap. Therefore, in the same device, the number of high-frequency antennas can be greater than the number of low-frequency antennas, and since high-frequency antennas and low-frequency antennas can be arranged in the same area, the layout of multiple antennas is more flexible.

[0046] According to an embodiment of the present invention, the first horizontal portion 115 of the first antenna 110 and the second horizontal portion 125 of the second antenna 120 may belong to the same conductive layer. In other embodiments, the first horizontal portion 115 may belong to a first conductive layer, and the second horizontal portion 125 may belong to a second conductive layer different from the first conductive layer.

[0047] Figure 9 A cross-sectional view of an antenna system 900 is shown according to another embodiment of the present invention. Figure 9 In the antenna system 900, the first horizontal portion 115 and the second horizontal portion 125 can be different conductive layers. (Top view of the antenna system 900) Figure 8 Similarly, each second horizontal section 125 may be arranged in the aperture of the first horizontal section 115.

[0048] Figure 10A cross-sectional view of an antenna system 1000 is shown according to another embodiment of the present invention. The antenna system 1000 is similar to the antenna system 900, and the antenna system 1000 further includes an electromagnetic bandgap layer 1010. The electromagnetic bandgap layer 1010 can reduce surface waves W1 and W2 to improve the performance of the antenna system 1000. Figure 10 In the example, the region 1015 in layer 106 located below the first horizontal portion and the second horizontal portion of the first antenna 110 and above the second reference layer 128 can be preserved without filling or setting the electromagnetic bandgap layer 1010 (i.e., the electromagnetic bandgap layer 1010 has cavities / pores 1015, and the first horizontal portion and the second horizontal portion are located within the boundaries of the cavities / pores 1015 of the electromagnetic bandgap layer 1010) to allow the transmission of the second wireless signal S2.

[0049] Figure 11 A cross-sectional view of an antenna system 1100 is shown according to another embodiment of the present invention. Compared to the antenna system described above, in the antenna system 1100, the first antenna 110 may further include a third horizontal portion 113, and the second antenna 120 may further include a fourth horizontal portion 124. The third horizontal portion 113 may be used to access a third radio signal S3. The third radio signal S3 may be in a third frequency band, wherein the frequency in the third frequency band may be lower than the frequency in the second frequency band. The fourth horizontal portion 124 may be used to access a fourth radio signal S4. The fourth radio signal S4 may be in a fourth frequency band, wherein the frequency in the fourth frequency band may be higher than the frequency in the first frequency band and the frequency in the third frequency band. The antenna system 1100 may optionally include an electromagnetic bandgap layer 1010 to reduce surface waves W1 and W2; however, the electromagnetic bandgap layer 1010 may be omitted if the performance is sufficiently good.

[0050] Figure 12 It shows Figure 11 The diagram shows the scattering parameters of the antenna system 1100. Curve C1 represents the scattering parameters of the first antenna 110, and curve C2 represents the scattering parameters of the second antenna 120. A trough LB1 may correspond to a first frequency band, and a trough LB2 may correspond to a third frequency band, wherein the trough LB2 may be generated by a third horizontal section 113. A trough HB1 may correspond to a second frequency band, and a trough HB2 may correspond to a fourth frequency band, wherein the trough HB2 may be generated by a fourth horizontal section 124. Therefore, the frequency band of the first antenna 110 can be widened by the third horizontal section 113, and the frequency band of the second antenna 120 can be widened by the fourth horizontal section 124.

[0051] exist Figure 11 and Figure 12In the present invention, both the first antenna 110 and the second antenna 120 include two horizontal portions. However, in other examples, one of the first antenna 110 and the second antenna 120 may include two horizontal portions, while the other of the first antenna 110 and the second antenna 120 may have only one horizontal portion, and the present invention does not limit this.

[0052] Figure 13 A top view of an antenna system 1300 is shown according to another embodiment of the present invention. Figure 13 In the first horizontal section 115, the first horizontal section 115 is cross-shaped and includes four fins. Each of the second horizontal sections 125 is located within the area enclosed by two adjacent fins of the first horizontal section 115. Therefore, in the same device, the number of high-frequency antennas can be greater than the number of low-frequency antennas, and the antenna layout is more flexible.

[0053] Figure 14 A cross-sectional view of an antenna system 1400 is shown according to another embodiment of the present invention. A first horizontal portion 115 may include a first arm 1151 and a second arm 1152. The first antenna 110 may further include a first feed assembly 116, which is separate from the first arm 1151 and the second arm 1152, for accessing a first transmitted signal S10 corresponding to a first wireless signal S1. Figure 14 In the second antenna 120, the horizontal portion 125 is connected to its corresponding power supply component. However, in some variant embodiments, similarly, the second horizontal portion 125 may include a first arm and a second arm, and the corresponding second power supply component of the second antenna 120 is separate from the first arm and the second arm of the second horizontal portion 125 for accessing the second transmission signal S20 corresponding to the second wireless signal S2.

[0054] Each of the first antenna 110 and the second antenna 120 may include a patch antenna, a dipole antenna, a planar inverted-F antenna (PIFA), a monopole antenna, a slot antenna, and / or an aperture antenna.

[0055] Figure 15 A top view of an antenna system 1500 is shown according to another embodiment of the present invention. Figure 15In the antenna system 1500, some of the second antennas 120 are surrounded by the first antennas 110, while others are positioned outside the boundaries of the first antennas 110. Therefore, the number of second antennas 120 can be greater than the number of first antennas 110. The antenna system 1500 may include m first antennas 110 and n second antennas 120, where m and n are integers greater than 1, and m < n. In the antenna system 1500, a first radio signal S1 accessed by the first antennas 110 may be transmitted and / or received in the air through the first horizontal section 115 and the first reference layer 118, and a second radio signal S2 accessed by the second antennas 120 may be transmitted and / or received in the air through the second horizontal section 125 and the second reference layer 128. Therefore, compared to an antenna array formed using the first antennas 110, the second antennas 120 (for accessing higher frequency radio signals) can form an antenna array with more antennas.

[0056] Figure 16 A cross-sectional view of an antenna system 1600 is shown according to another embodiment of the present invention. Antenna system 1600 and... Figure 1 The antenna system 100 is similar; however, the second reference layer 128 is disposed below the second horizontal portion 125 and not below the first horizontal portion 115. Accordingly, the region of the second reference layer 128 can be determined.

[0057] In summary, by setting the second reference layer 128, the lower-frequency first antenna 110 and the higher-frequency second antenna 120 can be placed in the same region, and the number of second antennas 120 can be greater than the number of first antennas 110. This invention also provides a solution for reducing unwanted surface waves to improve performance. In applications such as 5G millimeter-wave (mmWave) technology, the above-described antenna system (e.g., by means of the second reference layer 128) can reduce problems such as low antenna efficiency, large antenna pattern distortion, mutual coupling between different antenna arrays, weak resonance, and low antenna gain.

[0058] The use of ordinal terms such as “first,” “second,” and “third” in the claims to modify claim elements does not in itself indicate any priority, precedence, or order of one claim element relative to another claim element, or the chronological order of the execution of method actions. Rather, it is merely used as a marker to distinguish one claim element with the same name from another element with the same name.

[0059] While the invention has been described by way of example and according to preferred embodiments, it should be understood that the invention is not limited to the disclosed embodiments. Rather, it is intended to cover various variations and similar structures (as will be apparent to those skilled in the art), such as combinations or substitutions of different features in different embodiments. Therefore, the scope of the appended claims should be given the broadest interpretation to cover all such variations and similar structures.
