Compact Microstrip Patch Antenna Array Design for 5G Wireless Communication

This work presents mmWave compact microstrip patch antenna array design for 5G wireless communication. First of all, antenna element with form factor of 18.4×13.0×0.787 mm3 is designed by using CST MWS. The designed antenna element resonates at resonating frequency of 10 GHz with minimum return loss of −30 dB. In this element the peak realized gain of 5 dBi, total efficiency 62% and acceptable VSWR<2 is observed. After that 1×4 antenna array is designed which has maximum bandwidth of 500 MHz and peak realized gain of 11 dBi. The designed antenna array efficiency, gain and equivalent circuit modelling is also presented and discussed. Overall, the designed inset fed microstrip patch antenna array can be integrated to 5G wireless communication devices.
