Abstract

This paper elucidates the simulated and analyzed designs of 4 element microstrip patch antenna arrays along with Quarter wave transformer feed which is to be used in Wireless applications in the ISM frequency bands. The paper focuses on different microstrip array antennas such as corporate feed, Quarter wave transformer feed, resonant \((\uplambda/2)\) spacing and element spacing \((\uplambda/2)\) which are simulated, analyzed and designed using HFSS 13.0 and fabricated by photolithography technique using the FR4 substrate. Patch is tested using Vector Network Analyzer E5071C. The various antenna parameters decide the optimum feeding system. The designed antennas are 1 × 4 arrays. Quarter wave transformer feed is used for better characteristic feature and the usage of which declines the reflection coefficient up to −16.767 dB. There is a direct improvement in gain up to 6.0643 dB and directivity up to 10.340 dB. With the help of Quarter wave transformer feed the bandwidth of an antenna can extend up to 116.6 MHz. We get the optimum return loss data with good matching and efficiency, with high gain, band width and reject bands by using Quarter wave transformer feed. The experimental results prove that the proposed antenna is a good candidate for applications in WLAN communication system.
