Design and Simulation of Curved Edge Patch Antenna for Ka Band Application

Abstract: The aim is to study and design various rectangular microstrip patch antennas for wireless communication systems and to study the effect of various antenna parameters like Patch Length (L), Patch Width (W), substrate material, relative dielectric constant, substrate thickness etc. In the proposed research work antenna is designed and simulated to work in Ka band i.e. 26 GHz to 40 GHz. Various substrate material such as arlon, roger, and Al₂O₃ were considered for design process. Two resonant frequencies were observed in case of roger substrate and multi frequency bands are observed in case of Al₂O₃ substrate. Keywords: Microstrip, Patch Length (L), Patch Width (W), Substrate Material, Relative Dielectric Constant
