A Quadra-Port Circular-Patch Antenna with DMS/DGS Designed on thin Substrate for WLAN And Satellite X-Band Wireless Applications

The research includes single, and Quadra-port
$\text{MIMO}._{5.50/7.50\text{GHz}}$
antenna radiating EM wave designed for WLAN and Satellite X-Band applications. The thin substrate with height of 0.254mm is used where radiating-patch with defected-microstrip-feedline is printed on top-plane and defected ground on opposite plane for electromagnetic energy radiation. The single-port dimension is
$14\times 20\ \text{mm}^{2}$
and four-port
$\text{MIMO}_{5.50/7.50\text{GHz}}$
is
$28\times 40\ \text{mm}^{2}$
. The single-port produces bandwidth of 5.00GHz-10.0GHz while its
$\text{MIMO}_{5.50/7.50\text{GHz}}$
counterpart achieves bandwidth of 5.50GHz-11.61GHz. The
$\text{MIMO}_{5.50/7.50\text{GHz}}$
configuration maintains isolation of more than 14.0dB with peak gain of 3.0dBi at single-port and 4.50dBi in four-port
$\text{MIMO}_{5.50 / 7.50 \text{GHz}}$
. The diversity parameter includes
$\text{ECC}_{5.50 / 7.50 \text{GHz}} < 0.001, \text{DG}_{5.50 / 7.50 \text{GHz}} \approx 10.0 \text{dB}, \text{TARC}_{5.50 / 7.50 \text{GHz}}<{-}$
4.0dB,
$\text{CCL}_{5.50 / 7.50 \text{GHz}}<0.05 \mathrm{b} / \mathrm{s} / \text{Hz}$
and
$\text{MEG}_{5.50 / 7.50 \text{GHz}} \approx 0.0 \text{dB}$
. The proposed high-speed MIMI5.50/7.50GHz can be deployed in low frequency application infrastructure.
