Radome Effects on X-band Horn Antenna

This article presents an analysis of the effects of radomes on the performance of X-band horn antennas. The return loss, gain and beamwidth values of the antenna are systematically analyzed as a function of radome design parameters such as complex permittivity, thickness, curvature and distance from the antenna. The analysis is performed through electromagnetic simulation using the finite element method. The results show that the return loss of the horn antenna in the X-band is significantly affected by the thickness of the radome, and therefore, the design parameter must be chosen based on the operating frequency of the antenna. Furthermore, the presence of the radome also affects the antenna gain and beamwidth values. These findings provide valuable information to improve the performance of the antenna in the presence of dielectric radome.
