Abstract
In this research, a single band micro-strip square patch antenna at 28GHz is proposed. The design of patch antennas are very efficient and widely used in wireless communication due to their lower cost of fabrication, light weight and can operate at microwave frequencies but it offers low efficiency, low gain etc. Future upcoming 5G wireless communication is needed of high gain, good protection from path loss because of their millimetre wavelength of antennas. The main features of this proposed antenna are its very low return loss (S11), high gain, better efficiency and higher bandwidth are of 57 dB, 10.3 dBi , 97% and 4.3GHz respectively which makes it appropriate for 5G wireless communication. The proposed square patch antenna is designed and simulated using CST Microwave studio at operating frequency of 28 GHz. The gain of the antenna is improved by using air substrate. The proposed antenna design gives results of a very low return loss of 57 dB by which the antenna can provide high radiation power in 5G communication.
