Abstract

Objective: This research paper focuses on the simulated design and its analysis of 2 element microstrip patch antenna arrays with Quarter wave transformer feed and mitered bend feed network that is widely used in ISM frequency bands in the field of wireless communications. Methods: Various types of microstrip array antennas using Quarter wave transformer feed and with miter bend feeds are designed using HFSS 13.0 and fabricated by photolithography technique using FR-4 substrate, which is tested using VNA E5071C. Findings: The optimum performance of the feeding system is based on various antenna parameters. Here 1X2 array antennas are designed. Miter bends are used for better impedance matching. Usage of miter bends declines the reflection coefficient. There is improvement in gain by using miter bend feed network. Applications: Good impedance matching, optimum reflection coefficient and high gain are achieved by metered bends. The obtained results show that the designed antenna is an apt tool for communications.
