【摘要】 本文设计了一种基于半模基片集成波导(HM-SIW)的平面漏波天线以用于高阶轨道角动量(OAM)模式复用。天线的设计建立在?90°馈电的环形谐振腔基础上。文章首先分析了谐振腔的原理和模式,并利用该谐振腔产生和辐射无线频段的OAM波束。本文采用HFSS仿真设计分析了10GHz的HMSIW平面漏波天线实现了多个OAM模式的复用。更多还原

【Abstract】 A compact half-mode substrate integrated waveguide(HM-SIW) leaky-wave antenna(LWA) of different high-order orbital angular momentum(OAM) modes is presented in this paper in order to multiplex multiple beams. The LWA is based on a cavity resonator with two feeds of ±90°phase difference. The principle and mode analysis of the resonator is discussed, which give solutions to generating OAM beams of high-order modes on planar antenna at radio domain. The model is designed and simulated using full-wave analysis software.更多还原
