Abstract
This paper presents a proposed a Dual-Band T-Slot Microstrip Patch Antenna for sub-6GHz 5G application. The proposed antenna is designed to operate at two frequency bands of 5.923 GHz and 7.444 GHz respectively. The size and feed technique are determined by design formulas. The simulation results show a good return loss (reflection coefficient) of -33.696 dB and -18.464 dB respectively which is way below the benchmark of 10dB. The gain and VSWR results are 5.45dB and 1.049 at 5.933GHz; 4.158dB and 1.272 at 7.443GHz respectively. The CST software is used for the simulation.
