Miniaturized Micro-strip Antenna for 5th Generation Applications

This article presents a lightweight rectangular microstrip antenna which is developed for 5G communication systems. The resonance frequency is selected as 28 GHz for 5G use. FR4 epoxy material with a permittivity of 4.4 is selected as substrate material which has low cost and substrate size is $5.5\times 4.5$ mm2. The shape of the radiating patch is rectangular and using the microstrip feeding technique. HFSS software is used for the simulation. Different parameters are observed, such as return loss, Gain, and radiation pattern. The antenna has a gain of over 2.9 dB which is very useful for 5G communications.
