High-Performance 60 GHz Microstrip Patch Antenna with Innovative Parasitic Structures and Slot Configurations

This research article introduces an innovative microstrip modified rectangular antenna tailored for V-band applications. At its core, a radiating rectangular monopole is employed in the antenna design, precisely tuned to resonate at frequency of 60 GHz, achieving an impressive return loss of -36.23 dB. The design features an innovative configuration comprising interconnected rectangular and circular patches arranged in the distinctive shape of a swastika, a symbol revered for its cultural significance representing peace. Fabricated on a substrate of Rogers RT/Duroid 5880, renowned for its high performance at 0.254mm thickness. It covers a wide range of frequency from 58.49 GHz to 62.41 GHz and was designed using the advanced HFSS software. This design achieves an optimal impedance profile with a resistance of 49.90 ohms and a reactance of only 1.5 ohms. The antenna shows excellent diversity capabilities, making it ideal for 5G devices and applications in mobile networks and wireless technologies. This study examines important characteristics like the antenna's radiation patterns in different directions (E-plane and H-plane), as well as measures like VSWR and reflection coefficients or S-Parameter.
