The panel antenna can realize free selection of various polarization modes, solves the problem that the panel antenna needs to be replaced when the antenna receives and transmits electromagnetic wave signals with different polarizations, and saves communication cost.
Example two
On the basis of the above-described embodiment, referring to fig. 2, the first signal transmission circuit 101 includes the first microstrip circuit 1011, the second microstrip circuit 1012, and the third microstrip circuit 1013 connected in this order. The second signal transmission circuit 102 includes a fourth microstrip circuit 1021 and a fifth microstrip circuit 1022 connected in this order. The third signal transmission circuit 103 includes a sixth microstrip circuit 1031, and the sixth microstrip circuit 1031 is connected to the first microstrip circuit 1011 and the fourth microstrip circuit 1021.
The impedance of the first microstrip circuit 1011, the second microstrip circuit 1012, the third microstrip circuit 1013, the fourth microstrip circuit 1021, and the fifth microstrip circuit 1022 are all 50 ohms, and the length thereof is all 1/4 wavelength. The impedance of the sixth microstrip circuit 1031 is 70.7 ohms. That is, the first signal transmission circuit 101 has a length of 3/4 wavelength, and the second signal transmission circuit 102 has a length of 2/4 wavelength, which are different by 1/4 wavelength. Therefore, the third signal of the third signal transmission circuit becomes the first signal and the second signal with the same magnitude and the phase difference of 90 degrees after being transmitted by the first signal transmission circuit and the second signal transmission circuit; or the first signal and the second signal which have phases different by 90 degrees are transmitted by the first signal transmission circuit and the second signal transmission circuit to be changed into a third signal.
Illustratively, when the panel antenna transmits a signal, the rf circuit provides a transmission signal and transmits the transmission signal to the third signal transmission circuit 103, and the third signal transmission circuit transmits the received transmission signal (third signal) to the first signal transmission circuit 101 and the second signal transmission circuit 102, because the lengths of the first signal transmission circuit 101 and the second signal transmission circuit are different by 1/4 wavelength, the first signal transmitted through the first signal transmission circuit 1 and the second signal transmitted through the second signal transmission circuit 2 have the same magnitude and the phase is different by 90 degrees, and if the first signal transmission circuit 1 is electrically connected to the first feeding point 201 and the second signal transmission circuit 2 is electrically connected to the second feeding point 202, the radiation plate 20 of the panel antenna 100 transmits a circularly polarized electromagnetic wave signal through the two feeding points (201, 202). If only the first signal terminal 1 and the first feeding point 201 are electrically connected and the second signal terminal 2 and the second feeding point 202 are not electrically connected, the radiation plate 20 of the panel antenna emits a horizontally polarized electromagnetic wave signal through the first feeding point 201. If the first signal terminal 1 and the first feeding point 201 are not electrically connected and only the second signal terminal 2 and the second feeding point 202 are electrically connected, the radiation plate 20 of the panel antenna 100 emits a vertically polarized electromagnetic wave signal through the second feeding point 202. When the panel antenna transmits signals, the process is reversed.
Specifically, with continued reference to fig. 2, the first signal terminal 1 of the first signal transmission circuit 101, the third signal terminal 3 of the second signal transmission circuit 102 and the geometric center of the signal transmission circuit board 10 are located on a first straight line L1, and the second signal terminal 2 of the second signal transmission circuit 102 and the geometric center of the signal transmission circuit board 10 are located on a second straight line L2, wherein the first straight line L1 and the second straight line L2 are perpendicular to each other, and the vertical foot is located at the geometric center of the signal transmission circuit board 10.

Because the first signal transmission circuit 101, the second signal transmission circuit 102 and the third signal transmission circuit 103 of the signal transmission circuit board 10 in the panel antenna 100 are all formed by microstrip circuits, materials are saved, and manufacturing cost and labor cost are reduced.
