Design and Development of 3D Printed Omnidirectional Patch Antenna for Mobile Communication

This research aims to present a specially created 3D-printed omnidirectional patch antenna suitable for mobile communication in rural as well as urban areas under specific bandwidth. It operates effectively at central frequencies of 38GHz and 54GHz, offering respective bandwidths of 1.94GHz and 2GHz. The proposed 3D-printed omnidirectional patch antenna's three sections-front, rear, and top-combine to form a distinctive and useful antenna construction. Six mm is the length, 6.25 mm is the breadth, and 0.578 mm is the thickness of this entire antenna. As new wireless communication technologies are developed, antennas will need to have outstanding characteristics, including minimal losses, wide bandwidth, and high gain. Layer by layer, Creations are assembled together by 3D printing using an additive technique that makes it possible to produce antennas with three-dimensional shapes more quickly, cheaply, and adaptable. As a means for better 3D patch antenna strength, a novel concept for a 3D-printed microstrip patch antenna is presented in this study. When building an antenna, FR4 is utilized as its substrate, and copper silk filament is used to create a patch. The proposed antenna design undergoes rigorous simulation using HFSS software for performance validation, and then the antenna is tested with the help of a vector analyzer.
