Abstract
This paper presents a square shape Split Ring Resonator (SRR) loaded with micro strip patch antenna operating in UWB (Ultra Wide Band) range (3.1GHz -10.6GHz) for Bio-medical applications. The Ultra-Wideband is a wireless technology which is used to send large data over a wide range of frequencies by using very narrow pulses at low PSD (Power Spectral Density). UWB provides wireless transmission of audio, video and data with wide bandwidth. The proposed antenna specifically operates at 4.1GHz and is designed on a 23.19mm x 23.19mm x 1.35mm board of Arlon AD1000 substrate. This SRR antenna has been simulated using High-Frequency Structure Simulator (HFSS) software. The results show enhanced performance in terms of high gain, return loss (<10dB), Voltage Standing Wave Ratio (VSWR)<2, low Specific Absorption Rate (SAR), high Directivity, high radiation Efficiency.
