Design & Implementation of a Meta-Material Based Ultra-Wide Band Microstrip Patch Antenna for Vehicular Communication

Abstract

This paper presents an innovative microstrip antenna of compact dimensions, constructed utilizing advanced meta-materials tailored specifically for Ultra-Wideband (UWB) applications. The antenna design features two distinct meta-material surfaces, each intricately fabricated with engraved pi-shaped slits on the radiating plane and cross-shaped slits on the ground plane. The distinctive left-handed behavior exhibited by this meta-material originates from the collaborative interplay of capacitive and inductive effects engendered by the radiating and ground planes. The proposed antenna structure assumes the form of 30.8 x 27.6 x 0.8 mm³ and interfaces seamlessly with a 50Ω feed line via an SMA connector. Its electrical resistance encompasses a range extending from 3.5GHz to significantly beyond 14.5GHz, characterized by pronounced emission along the reference axis and a focused radiation pattern, distinctly enhancing frequency-related attributes. The fundamental objective driving the design of this antenna lies in its potential to facilitate uninterrupted communication among vehicles, a crucial aspect in vehicular communication applications. This goal necessitates a broad frequency spectrum to establish seamless connectivity in vehicular contexts. A thorough analysis of the research techniques, findings, and consequences was also provided, providing insights into the bright future of metamaterial-based antennas in vehicular communication.
