Abstract:
In this paper, a 28 GHz broadband microstrip patch antenna (MSPA) for 5G
wireless applications is presented. The Rogers RT/Duroid5880 substrate
material, with a dielectric constant of 2.2, the thickness of 0.3451 mm, and
loss tangent of 0.0009, is used for the studied antenna to operate at 28 GHz
center frequency. The proposed design of antenna is simulated by using CST
studio suite. The simulation results highlight that the studied antenna has a
return loss of -54.49 dB, a bandwidth of 1.062 GHz, a gain of 7.554 dBi.
Besides, radiation efficiency and the sidelobe level of the proposed MSPA
are 98% and -18.4 dB, respectively. As compared to previous MSPA designs
reported in the recent scientific literature, the proposed rectangular MSPA
has achieved significantly improved performance in terms of the bandwidth,
beam-gain, return loss, sidelobe level, and radiation efficiency. Hence, it is a
potential contender antenna type for emerging 5G wireless communication
applications
