Conformal Patch Antenna Array for ISM Band

Today microstrip patch antenna is gaining popularity in many applications due to its conformal and planar structure. Further, due to its ease of fabrication, miniaturized design, and its flexible feeding technique, it is extensively used in many applications like cellular communication, radar, satellite communication, airplanes, missile, etc. However, gain achieved using single patch antenna is not sufficient to be used in abovementioned applications. Desired gain can be achieved by using array of antenna. But impedance matching between sources and patch antenna elements is major requirement for using array of antennas for enhancing the gain. In this study, impedance matching between patch element and source is proposed by using microstrip lines. The structure of proposed antenna is analyzed using high-frequency structure simulator (HFSS). The achieved overall gain of this antenna is 9 dB which is significant for using it in Wi-Fi applications.
