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.
