Design of High Gain, Twin-band Antenna with CSRR for 5G Applications

A twin-band microstrip antenna with CSRR in the ground plane suitable for 5G wireless technology is presented in this article. The antenna radiates from 26.9GHz to 27.5 GHz with center frequency at 27.3GHz and from 29.3GHz to 29.9GHz with center frequency at 29.5GHz with peak realized gain of 7.25dB and 7.45dB respectively. The antenna applies twin slots on the patch and CSRR in the ground plane for improved stability and gain. The antenna is fabricated on RT Duroid 5880 of thickness 0.8 mm. The simulation is carried out in HFSS, which employs the method of finite element. For getting the optimized result, HFSS’s optometric analysis is also used.
