Embodiment 2
[0026] When the operating frequency of the antenna is high, if the antenna radiator is made of a metal plate, the antenna current will only flow along the longitudinal edge of the plate. Based on the super-skin effect of high-frequency current, the plate edge of the reflective panel 20 can be cut into concave-convex arc tooth shape instead of a hollow dragon shape, and the effect characteristic of low-frequency extension can still be achieved.
[0027] A loading circuit 19 may also be connected between the lower part of the double-sided copper-clad reflective panel and the metal conductor antenna base 6 .
Embodiment 3
[0029] The antenna radiator electrically connected to the microstrip antenna in the present invention may be a linear antenna or a planar antenna parallel to its radome.
[0030] The loading circuit may be composed of a resistor, or a resistor, an inductance coil, or a series or parallel equivalent circuit of a resistor, an inductance coil, or a capacitor. Or the equivalent circuit of a low-pass filter. The loading circuit is specifically defined in relevant textbooks.
