specific Embodiment
[0044] But relatively speaking, on-street parking mainly adopts side-on-street parking, so if figure 1 , figure 2 , image 3 In the example shown, it is a specific embodiment of the system of the present invention for parking on-street in a lateral position. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0045] Since the signal transmission between the transmitting antenna and the receiving antenna is affected by the direction of polarization, in order to further improve the flexibility of electronic tag installation, the antenna array 111 includes two sets of strip antennas 113 perpendicular to each other. The strip antennas 113 are parallel to each other, and one group of axes is perpendicular to the corresponding road surface; the plane where the antenna array 111 is located is perpendicular to the corresponding road surface and parallel to the driving direction of the corresponding road surface.
