A Two Arm Metamaterial Inspired Antenna with Compressed Size and Comprehensive Bandwidth

A two arm metamaterial (MTM) inspired antenna with compressed size and comprehensive bandwidth is presented. The Metamaterial based antenna is designed for some improvement in the performance of directivity gain, return loss and size of circuit area. The antenna consists of two TL-MTM arms been designed and fabricated to operate between 2 GHz-4 GHz. Each arm consist of a microstrip transmission-line loaded with five square inductors through an embedded series meandered line. The aim of the project is to design and fabricate metamaterial antenna and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Dielectric constant (εr), substrate thickness on Radiation parameters of Band width. Low dielectric constant substrates are generally preferred for maximum radiation.Our results have shown that the metamaterial substrate broadened the bandwidth of the antenna from 20.6% to 40.5% (more than -10 dB). Desired Patch antenna design is initially simulated by using IE3D simulator and Patch antenna is realized as per design requirements.
