5G Antenna at Millimeter Wave Frequency

Designing compact antennas operating at 5G millimeter wave bands is an emerging research area in the era of wireless communication. This research paper presents the designing, simulation as well as measurement of microstrip patch antenna functioning at 28 GHz. The proposed antenna has dimensions of 12 x 15 x 0.508 mm
³
and is resonating at 28 GHz with measured reflection co-efficient of -17.05 dB, bandwidth of 1.23 GHz and gain of 7.4 dB. The measurement results demonstrate the suitability of the proposed design for 5G wireless applications at millimeter wave band.
