Abstract

In this paper, a 1x8 coupled microstrip patch array antenna capable of providing high gain and operating between 24 GHz to 28 GHz is designed for 5G mobile applications. The proposed array antenna consists of eight antenna elements, with each single antenna element achieves simulated average return loss of less than 10 dB from 24.125 GHz to 28.131 GHz. The simulated peak realized gain of the proposed array antenna is 15.6 dBi at 0 degree. In addition, four identical 1x8 subarrays with each providing 900 coverage are arranged in 4 different directions to provide 3600 coverage. The single microstrip patch antenna element and four identical 1x8 subarrays antenna are fabricated where the overall size suitable for implementation in 5G smartphone applications.
