Abstract

Thispaperpresentsacompact55×20mm2widebandmulti-input-multi-output(MIMO) antenna. The proposed structure consists of two antenna elements excited using CPW feeding technique and is printed on a low cost and easily available FR4 substrate. In the proposed MIMO design, the first antenna at port 1 is fixed in its position and orientation while, the second antenna at port 2 is placed in six different orientations by keeping the overall dimension constant. The observationismadeonthevariationintheinsertionlossastheorientationofthesecondantennais altered. With this analysis, the orientation of second antenna element giving the least interference and insertion loss is proposed, and all the parameters are studied. The proposed design exhibits anaveragepeakgaingreaterthan2.8dBi,envelopecorrelationcoefficient(ECC)lessthan0.0001, insertion loss less than -38dB and stable radiation patterns over the entire wide bandwidth. The antenna operation (i.e. |S11| and |S22|<-10dB) ranges from 4.1 to 6.4GHz at port 1 and 4.35 to 6.5GHzatport2,therebymakingtheantennasuitableforWirelessLocalAreaNetwork(WLAN) andWirelessFidelity(Wi-Fi)applications
