Geo-textile Based Metamaterial Loaded Wearable Mic rostrip Patch Antenna

Abs tract- In this paper, a geo-textile material that is polypropylene based metamaterial loaded wearable T-shaped microstrip patch antenna for public safety band applications is presented. Under unloaded condition of T-shaped microstrip patch antenna, poor matching is observed in the public safety band. Further, this antenna is loaded with metamaterial split ring resonators (SRRs). This loading provides better matched condition in the public safety band. In loading condition, the antenna resonates at 4.97 GHz with the bandwidth and gain of 50 MHz and 6.40 dBi respectively. The electrical dimension of the proposed wearable antenna is 0.369 λ × × × × 0.369 λ. The antenna is fabricated, tested, and the measured results are presented in the paper. An equivalent circuit of the designed antenna under loading condition is also prepared and analyzed.
