Design and Analysis of SRR-Inspired Ultra Wideband Antenna

The paper presents a compact and low cost SRR-based ultra wideband (UWB) antenna for wireless communication. The proposed antenna has the operability to cover the UWB range from 3.1 to 10.6 GHz. It is design on Forgotten Realms 4 (FR-4) substrate having a thickness of h = 1.6 mm with a trapezoidal-shaped feedline as well as ground plane. Radiating patch consists of splits rings are utilized in the regular 8-sided polygon to get better results. The proposed antenna with compact size of 22 × 32 × 1.6 mm3 is analyzed with the help of simulated results. In overall, UWB band antenna has steady radiation characteristics.
