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.
