Modified Triple Band Microstrip Patch antenna for Higher 5G bands

This paper presents the design of a modified triple band microstrip patch antenna operating at 28 GHz for Higher 5G bands. The proposed antenna consists of a modified rectangular ring with fork shaped strip. The antenna is designed with dimensions of 30×40×1.6 mm on a RT/Duroid 5880 substrate with a dielectric constant of 2.2. The proposed antenna design resonated at the triple frequencies 28 GHz, 31.45 GHz and 34.6 with -12.5114 dB, -16.5928 dB, -15.7107 dB return loss and covers -10 dB impedance bandwidth of 1.37 GHz (27.47-28.84 GHz) at 28 GHz, 0.11 GHz (31.38-31.49 GHz) at 31.45 GHz and 34.6 GHz (33.59-36.01 GHz), which covers the higher band of 5G mobile application. Further, the maximum gain of 3.7308 dB and VSWR of 1.6206, which is less than 2 and is acceptable to have for high frequency antenna with minimum signal loss at 28 GHz to be used in USA, Korea and Japan.
