24 GHz Conformal Antenna with Broad Beamwidth and Wideband for Detecting Target

Abstract

This paper presents the development and analysis of conformal antenna array for proximity fuse as one of the defense technologies. The main objective is to design a small antenna with broad beamwidth and wide bandwidth. The conformal array is designed as a truncated rectangular pyramid with five patches. The simulation results present significantly wide beamwidth in both E-plane and H-plane and 1 GHz bandwidth at 24 GHz. From the simulated results, the miniaturized conformal antenna array with tilted patches is beneficial to detect the target accurately and widely.
