Abstract: This paper presents the design and analysis of the compact patch antenna for 5G and future generation millimetre-wave communication system. The proposed design consists of FR4 substrate length, width, and height of 21.37 x 5 x 1.59 mm3 , besides two rectangular slots incorporated with a dimension of 0.2 x 2.6 mm2 within the patch of 4.22 x 3.46 mm2 , to enhance the resonance frequency more accurate and one more square slot incorporated in to feed line with the dimension of 0.2 x 0.5 mm2 . The obtained return losses of the design is-21.25dB with gain and voltage standing wave ratio (VSWR) of 3.90dBi,1.18 by using a lumped port configuration. For the specific absorption rate (SAR) evaluation considered as a human head model in high-frequency structure simulator (HFSS) software, the obtained values are within the standard limit, the design covers the frequency range of 28GHz, this design may capable of 5G and next-generation wireless communication system application.
