Abstract

A linear leaky-wave antenna with a fixed beam, containing a waveguide with a semitransparent narrow wall made of metal cylinders and a prism with constrained refraction of 15 metal waveguides, is proposed and studied using numerical simulations based on the finite element method in the Ansys HFSS software product. A compact three-channel waveguide power divider in the E-plane is proposed and investigated. Using numerical simulation, the characteristics of an antenna array containing a divider and three linear leaky wave antennas with prisms are investigated. It is shown that in a frequency band of more than 15%, the efficiency of the antenna array surface is more than 0.65.

摘要

提出并利用Ansys中基于有限元方法的数值模拟方法研究了具有固定波束的线性泄漏波天线，该天线包含一个具有由金属圆柱体制成的半透明窄壁的波导和一个具有15个金属波导的受约束折射的棱镜。 HFSS软件产品。提出并研究了E平面中的紧凑型三通道波导功率分配器。使用数值模拟，研究了包含分频器和三个带棱镜的线性泄漏波天线的天线阵列的特性。结果表明，在大于15％的频带中，天线阵列表面的效率大于0.65。
