Design and analysis of rectangular microstrip fatch antenna using metamaterial for WLAN application at 24 GHz

Abstract

This present technique show proposed metamaterial (MTM) structure is designed for better result in bandwidth and reduction in the return loss at operating frequency 24 GHz. The proposed antenna is designed on The proposed antenna is designed on low cost FR-4(lossy) substrate and this proposed antenna is fed by 50 Ω microstrip line and having dimension is 2935(L) Mm×299(W) Mm × 1.6(h) Mm by using CST MWS Software. This paper show Metamaterial structure is designed by rectangular SRR with thin wire loaded on Rectangular Mcrostrip patch antenna by using CST MICROWAVE STUDIO(computer simulation technology software). The bandwidth of metamaterial increased upto 1249MHz as comparison to RMPA and Return loss = -28076717dB. This antenna is more suitable for WLAN application in communication at 2.4GHz operating frequency in S-band.
