A Stacked Patch Antenna with Periodic EBG Structure and Switching-Beam Capability for 5G Applications

In this paper, a novel design of stacked aperture patch antenna array (SAPAA) incorporating planar Electromagnetic band gap structure for the 5G applications is presented. The proposed antenna array, working at 26 GHz band, has the switching beam capability achieved by PIN diodes, which act like switching components to control the beam steering by turning them ON and OFF. The proposed design was simulated using a multilayer structure of a 0.787 mm Rogers RO5SS0 and 0. 65mm ARIOOO substrates with a board size of 1$4^{\star}27^{\star}$1.542mm3. Simulation results show 3-direction radiation pattern reconfigurability with a gain of 8.4 dBi, and less than -10dB of return loss over the frequency band ranging from 24.6 GHz to 26.7 GHz. The main beam-scanning range is from -15° to +15°. The proposed antenna array represents a potential solution for the emerging 5G wireless applications.
