Analysis of Antenna-Radome System at Millimeter Wave Band

Abstract

In this paper, a Cassegrain monopulse antenna covered with a multilayered Von Karman radome at millimeter wave band is analyzed. The electrically large Cassegrain antenna with the aperture diameter about 38lambda0 is analyzed using ray tracing (RT) method and the radome with the length of 232lambda0 and base diameter of 82lambda0 is analyzed using aperture integration -surface integration (AI-SI) method. The curvature radius of the radome and the lateral transmission in the radome dielectric are considered in the analysis.
