A Novel High-gain Wide-band Omnidirectional Antenna for SatelliteCommunication Application

摘要

A novel antenna is proposed in this article, which has simple structure, high gain, wide-band, omni direction and small physical size characteristics. Through optimized design, the maximum gain in omnidirectional plane is 5.0dB, the 3dB beam width in the normal plane ≥400, the absolute VSWR band width of this antenna is 22.2GHz, and the relative VSWR band width is about 73% (VSWR<2), so the antenna can cover the K/Ka band. Because of the merits of the high gain and wide band, this antenna is not just used in the satellite communication, but also in the other domain such as the mobile communication.
