Design of a ‘Helicop’ Shaped Dual-Band Patch Antenna for 5G mm-Wave Wireless Communication Applications

This paper introduces a Helicop shaped dual -band patch antenna designed for the applications of 28/38 GHz 5G mm-wave wireless communication. The proposed antenna is made on Rogers RT5880 material and has dimensions of 7 mm x6 mm x 0.8 mm. The antenna employs rectangular Slots and Stubs positioned identically within the patch, along with the slots in the ground, The 28 GHz and 38 GHz frequencies are where the antenna is most suited to resonate. At these frequencies, it shows excellent performance, with return losses of -20.1 dB at 28 GHz and -19 dB at 38 GHz, while maintaining a VSWR of below 2 for the 28 GHz and 38 GHz bands. A dual-band patch antenna was modelled and analyzed through CST software. Keywords: return loss, 5G antenna, mm-wave, and wireless communication.
