A Parabolic Antenna with Multi-band and High-gain

In this paper, an antenna gain is improved by adding a parabolic reflector above the feed and using a rotating paraboloid to generate a strong directional radiation field. Based on the above method, the simulation and test results show that the directivity of the antenna is effectively enhanced at 3.6 GHz, 7.2 GHz and 10.8 GHz, and the gain is greatly improved to achieve high gain.
