[0003] The biggest advantage of the PIFA (Planar Inverted F-shaped Antenna) is that the feed position can be changed to adjust the input impedance to 50 ohms.

[0056] Please refer to Figure 1, which is an equivalent schematic diagram of a current inverted-F antenna. The biggest advantage of a planar inverted-F antenna is that the feed position can be changed, adjusting the input impedance to 50 ohms. When designing an inverted-F antenna, three main structural parameters determine the antenna's input impedance, resonant frequency, and impedance bandwidth. These three structural parameters are the antenna's resonant length L, the antenna's height H, and the distance S between the two vertical arms. This type of antenna can be used as a single-frequency, dual-frequency, or multi-frequency antenna, offering advantages such as low profile, large bandwidth, and small size. The disadvantage is that the radiation pattern is uncontrollable; good transmission and reception performance can only be achieved when the requirements for the radiation pattern are not high or not sensitive.
[0057] Please refer to Figures 2, 3, and 4 together. Figure 2 is a schematic diagram of the antenna structure provided in an embodiment of this application.

[0058] The antenna structure provided in this embodiment includes a substrate 11, a first switching device 12, a second switching device 13, and a radiator 14; the first switching device 12 and the second switching device 13 are disposed on the substrate 11, and a radio frequency module is disposed in the substrate 11; the first switching device 12 and the second switching device 13 are both electrically connected to the radio frequency module.
[0059] The radiator 14 includes a radiating section 141, a low-frequency feed section 142, and a high-frequency feed section 143. The radiating section 141 is connected to the low-frequency feed section 142 and the high-frequency feed section 143, and is spaced apart from the substrate 11. The low-frequency feed section 142 is electrically connected to a first switching device 12 to form a feed point. The high-frequency feed section 143 is electrically connected to a second switching device 13 to form another feed point. In this embodiment, by setting two different feed points, the radiator 14 can be optimized for high and low frequencies respectively, thereby expanding the antenna's operating bandwidth and enabling the antenna structure to operate effectively over a wider frequency range, meeting multi-band requirements. Simultaneously, by setting two different feed points, better impedance matching can be achieved for different frequencies, thereby reducing signal reflection and improving communication stability and anti-interference capabilities.
[0060] The first switching device 12 controls the connection between the low-frequency feed section 142 and the RF module, and the second switching device 13 controls the connection between the high-frequency feed section 143 and the RF module. The first switching device 12 and the second switching device 13 are RF switches used to control the opening and closing of the communication channels between the high-frequency feed section 143 and the low-frequency feed section 142 and the RF module. The two feed sections are spaced apart at the position of the radiating section 141. Different feed positions can be selected using the first switching device 12 and the second switching device 13, thereby changing the radiation mode of the antenna structure and adjusting the antenna pattern. This achieves controllability of the antenna pattern and ensures good radiation performance of the antenna structure within a specific frequency band.

In some embodiments, a metal ground layer is laid in the substrate 11, and the radiator 14 further includes a ground portion 144. One end of the ground portion 144 is connected to the radiator 141, and the other end of the ground portion 144 is electrically connected to the metal ground layer. The ground portion 144 is located near the end of the radiator 141, and a low-frequency feed portion 142 is located between the ground portion 144 and the high-frequency feed portion 143. As shown in Figure 5, the interval between the high-frequency feed portion 143 and the low-frequency feed portion 142 is L2. The radiator 14 can be made of metal, such as stainless steel or copper, which are low-loss, high-conductivity materials.
[0062] In this embodiment, a feed section is added to the ordinary inverted-F antenna, so that the antenna structure forms two different feed points, which can be optimized for high frequency and low frequency respectively, thereby expanding the working bandwidth of the antenna and enabling the antenna structure to work effectively in a wider frequency range to meet the requirements of multi-band.
[0063] Please refer to Figure 2. In some embodiments, a metal ground layer is provided on a portion of the surface of the substrate 11, and a bent portion 145 is formed at the other end of the grounding portion 144.

For example, a copper metal is laid to form a ground layer, and grounding is achieved by providing a grounding portion 144 in the radiating portion 141 and connecting it to the copper metal in the substrate 11. The grounding portion 144 is attached to the substrate 11 by providing the bent portion 145, using a planar patch grounding method to increase the contact area with the substrate 11 and ensure the balanced placement of the radiator 14.
[0064] In this embodiment, the radiating part 141 has a plate-like structure. The high-frequency feeding part 143, the low-frequency feeding part 142 and the grounding part 144 are disposed on the same side of the plate-like structure and are bent together with the radiating part 141. The radiating part 141 is parallel to the substrate 11, which facilitates the installation during the patching process.

One end of the high-frequency feed section 143 is connected to the radiating section 141, and the other end of the high-frequency feed section 143 is inserted into the second fixing hole 221. In this embodiment, the feed section is installed and connected by insertion, which can reduce the structural layout and reduce the coupling effect with ground.
[0068] The first fixing member 21 and the second fixing member 22 are base materials, so as to isolate the low-frequency feed section 142 and the high-frequency feed section 143 from the substrate 11, which is equivalent to the low-frequency feed section 142 and the high-frequency feed section 143 being hollowed out.
[0069] In some embodiments, a connector 15 is provided inside both the first fixing hole 211 and the second fixing hole 221.

The connector 15 is made of metal, and the low-frequency feed section 142 and the high-frequency feed section 143 establish an electrical connection with the corresponding first switching device 12 and second switching device 13 through this connector 15.
[0070] In some embodiments, a limiting notch 16 is provided at the other end of the low-frequency feed section 142 and the other end of the high-frequency feed section 143 to limit the insertion depth of the low-frequency feed section 142 and the high-frequency feed section 143, thereby limiting the distance between the radiating section 141 and the circuit board. In some embodiments, the antenna structure further includes a first microstrip feed line 17 and a second microstrip feed line 18, which are disposed on the substrate 11; a first switching device 12 is electrically connected to the RF module through the first microstrip feed line 17, and a second switching device 13 is electrically connected to the RF module through the second microstrip feed line 18. Thus, the low-frequency feed section 142 is electrically connected to the RF module through the first switching device 12 and the first microstrip feed line 17, and the high-frequency feed section 143 is electrically connected to the RF module through the second switching device 13 and the second microstrip feed line 18.
[0071] For different frequencies, the RF module is equipped with two channels: a high-frequency transmission channel and a low-frequency transmission channel. Correspondingly, two microstrip transmission lines are provided to connect the two different feed sections to the corresponding transmission channels in the RF module, so that the antenna structure can maintain effective operation in a wider frequency range and meet the requirements of multi-band.

In this embodiment, the first and second switching devices operate selectively. The processing chip selects to control the first or second switching device to be on according to the actual frequency band requirements, thereby selecting different feed positions, thus changing the radiation mode of the antenna structure, adjusting the antenna pattern, ensuring that the antenna structure achieves good radiation performance in a specific frequency band, thereby realizing the controllability of the antenna pattern and improving the communication performance of the electronic device.
