60 GHz Rectangular Patch Antenna with Cavity Resonator for 5G Applications

The main objective of this paper is to successfully design a microstrip rectangular-shaped antenna resonating at a frequency of 60 GHz. The model is designed based on 3D EM full-wave FIT-based CST Microwave Studio, aims to achieve a minimum return loss power rate lower than -10 dB with a frequency range between 56 to 68 GHz. A concept that offers solutions to a constantly changing radar and 5G application market. The proposed antenna will also include key elements such as an air cavity and a thick-film substrate for high-gain applications. Its structure also includes transmission lines (dimensions 4 mm × 2.7 mm) to improve antenna's ability in radiating signals resonating at 60 GHz out into open space. The unique design proposes to achieve a gain higher than 9 dB, a minimum return loss power less than -10 dB covering a 12 GHz bandwidth and directivity as power over 8 dBi. This high efficiency rate will be tested using Integral Equation solver software with high meshing.
