Design and Simulation of Nature-Inspired Patch Antenna with CPW Feed for Dedicated Short-Range Communication Technology Using HFSS EM Simulation Software

摘要

Microstrip patch antennas are one of the most widely used antenna structures in communication because of their small size but they also have a disadvantage of having a narrow bandwidth. Here, we have used the superformula given by Gielies, which is used to represent any natural shape mathematically. In this paper, the performance of a triple modified superformula-inspired patch antenna is investigated and all the results are systematically presented. The antenna is designed using Rogers RO4003 substrate (er = 3.55) and is excited using a CPW feed. The first bandwidth is of 53% at central frequency 1.23 GHz and the second bandwidth is of 52% at central frequency 5.93 GHz. The 5.9 GHz frequency is used by the dedicated short-range communication technology (DSRC). It is used to enhance the safety of transportation. The bandwidth, directivity, and gain have improved drastically than a circular patch antenna.
