Abstract
ABSTRACT-In this paper a D shaped substrate conformal patch antenna by coplanar waveguide(CPW)-FED is proposed for Radar applications. As it is a asymmetrical CPW fed antenna the design consists of D-shaped patch and ground plane of different lengths separated by a feedline on the same side of substrate .The antenna is designed with the material FR4_Epoxy substrate with dielectric constant 4.4 and thickness 1.59mm. As per the simulation results, the proposed antenna can resonate at frequencies 7.77GHz and 12.6GHz which are used for satellite communications. This antenna is simulated using HFSS (High Frequency Structure Simulation)software and the basic parameters of antenna such as return loss, radiation pattern, bandwidth are analysed. Keywords-CPW-Fed, Antenna, Radar, polarization, impedance.
