Abstract

In this work, the design of a dual-band microstrip patch antenna and antenna array for 5G (5th Generation) mobile communication applications is conferred. The prerequisite for 5G technology is higher data rate, enhanced efficiency, improved gain, wide bandwidth, and compact antennas. The Rogers RT/Duroid 5880 and FR4 substrate is used to design the proposed dual-band inset fed microstrip patch and antenna array resonates at mm-wave frequencies of 28,39.5 GHz and 29,49.8 GHz respectively. The dual-band single element antenna (Rogers) provided with 8.057, 7.337 dB, and 8×8 array antenna yields with 25.86, 26.28 dB superior gain and good impedance bandwidth of 1.5,4.3 GHz at 28 and 39.5 GHz resonating frequencies. Moreover, dual-band antenna and array antenna exhibits higher radiation efficiency and reflection coefficient of S11 less than -10 dB at both the frequency bands.
