Abstract

To meet the usage requirements of portable high-power, multi-beam jamming systems with large capacity, a multi-beam horn transmitting antenna array with ultra-wideband and wide-angle coverage is designed. Based on the beam network characteristics of the microstrip Rotman lens, the transmitting antenna array adopts the structure of an arc-shaped opening sectorial ridge horn antenna, achieving 16 beam outputs within the operating frequency range from 6 to 18 GHz and possessing excellent beam directivity. The elevation beam width is 40°~70°, and the azimuth realizes ±45° airspace coverage, having ultra-wide-angle beam coverage capability. The active standing wave ratio of the antenna array is less than 3.0, and it can withstand high power output. At the same time, the multi-beam horn transmitting antenna array structure is designed to be compact, facilitating usage and installation.
