Performance Analysis of Complementary Split Ring Resonator with Improved Four Element Antenna for X Band Wireless Applications

A very compact MIMO antenna for broad-band applications which covers the complete spectrum of X-band applications is represented here. The proposed element in the represented antenna covers a total volume of around 320 mm3. The isolation among radiating elements is improved by placing individual elements orthogonally thereby improving isolation better than 20 dB. This enhanced isolation helps to provide substantial MIMO parameters including ECC, TARC, channel capacity loss, and multiplexing efficiency. The devised antenna is compact (0.066 lambda x 0.066 lambda x 0.0024 lambda mm3) printed over an FR4 substrate which is widely available concerning 6.2 GHz to 11.2 GHz wireless applications. Fabrication of the above-mentioned proposed antenna is done, and all the desired calculations are made desirably. Furthermore, the practically measured results conclude that the antenna-measured patterns well correspond to the simulated results.
