A Four-Port Super-Wideband Monopole Antenna Including Multi-Band Wireless Applications for On-Body Applications with SAR Analysis

This communication reports the analysis of single, and four-port MIMO antenna with super-wideband characteristics. Including bandwidths of 8.32GHz-71.89GHz & 7.84GHz-73.292GHz respectively. The proposed antenna is designed on very thin RF-substrate and its four-port MIMO antenna design occupies space of
$24\times 24 \text{mm}^{2}$
. The impedance-bandwidth includes multiple narrow-bands such as X-Band, Ku-Band, K-Band, Ka-Band, Q-Band, U-Band and V-Band. The annular-ring forms the radiating patch printed on top-surface and defected-ground (DGS) on opposite surface. The proposed work is also subjected to SAR analysis for On-Body applications.
