A Super-wideband Flexible Four-Port MIMOsup Antenna for ON-Body Multi-Band Applications with Bandwidth Ratio 19.38:1

In this communication, a tapered-feed monopole antenna radiating EM energy with partial ground on a thin substrate is designed and analyzed for single as well as four-port MIMO
sup
antenna. The circular-patch and rectangular-ground is used to achieves super-wideband bandwidth of 5.158GHz-100.0GHz. The bandwidth is useful for wireless services including WLAN, X-band satellite communication, Ku-band, RADAR communication andmillimeter-Wavebands including n257, n258, n259, n260, n261, n262, n263. The identical four-radiating patch are placed orthogonally achieving isolation of more than 15.0dB and diversity parameters including ECCsup<0.01, DGsup≈10.0dB, TARC
sup
<-5.0dB and CCLsup<0.25b/s/Hz. The MIMO antenna also offersgain of 6.75dBi at 60.0GHz with desired 2-D radiation pattern.
