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.
