Design of Satellite Interference Signal Transmitting Antenna

In the paper, a kind of satellite interference signal transmitting antenna is introduced, the antenna array adopts the form of a cross array, the circular polarization is realized by wideband power division phase shifting network, and the array direction diagram is optimized by Taylor synthesis method. The array has the characteristics of wide operating frequency band, high gain and low sidelobe. The simulation results show that the antenna axial gain is greater than 12 dBi, side lobe suppression is greater than 25 dB, axis ratio is less than 3 dB, and it is suitable for a variety of satellite navigation interference transmitting.
