The Design of a Low Dielectric Constant Plate Microstrip Antenna

Abstract

This paper introduces a design of a low dielectric constant plate rectangular micros trip antenna. In order to meet the requirements of the radar simulator on antennas, a rectangular micros trip antenna whose dielectric plate is made of PTFE is designed, the relative permittivity of PTFE is 2.2. Emulating the antenna with software named ADS2011, simulation results show that, compared to the traditional microwave material named epoxy resin(FR4),whose relative dielectric constant is 4.4, the rectangular micros trip antenna has a higher gain, better suited for radar simulator.
