Abstract

In this paper, a probe fed PIFA square array antenna is designed for the fifth generation (5G) wireless applications in EU countries with an allocated frequency band of 24.25GHz - 27.5GHz. The array designed is made up of 16 elements arranged in a 4x4 matrix form, this makes it easily integrated into very portable mobile devices. An impedance bandwidth of 12.5% ranging from 24.25GHz - 27.5GHz was achieved and measured, with each element having a reflection coefficient of less than -15dB and a worse case 14dB mutual coupling. With a uniform amplitude and no inter element phase difference, a maximum broadside gain of about 16.71dB is obtained with an SLL(Side Lobe Level) of 12dB and a 3dB beamwidth of 30 deg. Scanning the main beam to 48 deg in the E-plane (y-z plane) the broadside gain reduces to 14.46dB with a phase difference of 150 deg per column element and an SLL of 6.86dB still maintain a good beam focus of 30 deg 3dB beamwidth. These good characteristics renders this antenna a good candidate to be deployed for 5G mobile applications.
