Superwideband Dual Notched Band Square Monopole MIMO Antenna for UWB/X/Ku Band Wireless Applications

摘要

In the presented manuscript, a compact antenna designed on Rogers RTDuroid 5880 substrate is presented which covers superwide bandwidth of 3.21GHz-19.43GHz. On one face of substrate, square monopole patches are printed and common ground on other side. Designed antenna is converted to dual notched band characteristics which mitigates Wireless Local Area Network (WLAN: 5.150GHz-5.825GHz) and Downlink Satellite System (DSS: 7.25GHz-7.75GHz) interference. These two notched bands are obtained by using inverted T-shaped stub and rotated C-shaped slot on radiating patch. Designed antenna has maximum gain of 5.33dbi and radiation efficiency of 86%. Far Field Radiation pattern shows omnidirectional and dipole like pattern in H- and E-plane. Diversity performance of MIMO antenna is also studied in terms of ECC (Envelope Correlation Coefficient), DG (Directive Gain) and TARC (Total Active Reflection Coefficient).
