Investigation of Patch Phase Array Antenna Orientation at 28 GHz for 5G Applications

In this paper, three different configurations of patch array antennas are designed to investigate their radiation patterns with different orientation and excitation phase at 28 GHz for 5G application. All antennas are fed by inset feed line. The excitation phases are changed to study the radiation pattern of each patch array antenna with different orientations. Simulated and measured S11, S12 and simulated radiation patterns are presented. The simulated result showed that the designed antennas are able to operate at 28 GHz. Antenna 1 and 2 provide beam shifting covers the angles up to 66°, while for Antenna 3 is 94°.
