Design and simulation of a rectangular patch microstrip antenna for the frequency of 28 GHz in 5G technology

Abstract

The development and application of the fifth generation mobile communication system (5G) requires and provides high-speed and high-capacity wireless communication services. This paper describes the design of small antennas using microstrip technology as a wireless communication device operating at a frequency of 28 GHz. The technique method used for antenna design is inset feed technique with a shift to the length of the transmission line on the side of the patch gap. Antenna design is used method of moment or simulation using CST software application. To support antenna design in the simulation process using the type of material substrates used was Taconic TLY-5 type. The results of simulations the obtained, such as: bandwidth of return loss ≤ -10 dB is 454 MHz, VSWR (2:1) is 1.03, beam width is 74.4 degrees and gain is 6.72dB. An antenna design obtained through simulation shows a simple and compact antenna shape with the expected parameter value. The design is a basic element of research for antenna sub arrays for increasing radiation power.
