| Abstract: | In this paper, a Gaussian distributed corrugated horn antenna is designed with high gain, high conversion effien?cy, low cross-polarization and stable phase center. The antenna can work in dual-linear or circular polarization, it adoptsorthogonal coaxial feed and has a simple and compact structure. With establishing the antenna simulation model accordingto parameter design, the whole horn antenna is optimized. The simulation and measurment results show that the antennahas a gain of greater than 20dBi in the frequency range of 34~36GHz, the side lobe level is not greater than -26 dB, andthe pattern has good symmetry on the E-plane and H-plane. The overall performance of the antenna satisfies the require?ments of engineering applications. |
