Characterization of Microstrip Patch Array Antenna at 28 GHz

Abstract

A Microstrip patch array antenna is presented and resonates at 28 GHz. It is a well-known antenna because of its easiness to manufacture with a high gain, easy on the pocketbook, as well as it has a simple structure. The substrate is based on the Rogers Duroid RT5880 with dielectric constant r 2.2 and the height of copper Hc 0.254 mm. In fact, the Computer Simulation Technology Microwave Studio 2015 software has been used as a technique for simulating in this project. The design of the 28GHz antenna is done according to the specification of ETSI. By selecting optimum parameters of proposed, the measured return loss of proposed antenna during design frequency (28 GHz) is -52.522 dB at 28.08GHz. In addition, the value gained is high, which is 21.1 dBi and the achieved bandwidth is 1120 MHz. Hence, the target of the antenna is for the KA-Band communication which can work on 5G communication.
