Design and Parametric Analysis of a Triple Band Waxing Crescent Moon Shaped Slotted Microstrip Patch Antenna for 5G Wireless Communications

In this article author designs a new and compact patch antenna with the dimensions 40x21x1 mm3 on substrate called FR4 with a dielectric constant of 4.4, sandwiched between a patch and a copper ground plane. Microstrip feedline is used to link the Moon-shaped antenna to the coaxial cable connection and the antenna's impedance is matched. slotted antenna has been found to resonate between the frequency bands of 23.67-24.82 GHz,25.46 -26.44GHz and 26.77-27.92 GHz at resonant frequency of 24.32 GHz ,25.91GHz and 27.36 GHz respectively. at all the resonant frequencies of 24.32 GHz ,25.91GHz and 27.36 GHz, VSWR of the proposed antenna is same with the value 1.06 dB. Microstrip feeding technique is used to create this microstrip patch design. This patch is being researched because it has a low VSWR at all the three resonant frequencies with high bandwidth. This design is suitable for triple band operations for wireless communication in the range of 5G frequency bands. By adopting an appropriate feeding mechanism and use of proper cutting slots in the rectangular patch, frequency band width can be increased. The electromagnetic simulation of the proposed antenna has been done using CST software. The analysis of performance will be based on changing the geometry of the patch and the obtained results are gain, VSWR, antenna efficiency and radiation pattern. After parametric analysis it is observed that this design is perfectly suitable for 5G wireless applications. KEYWORDS: Moon shape, Patch antenna, gain, 5G.
