QMSIW Based Self-Diplexing MIMO Antenna
A compact self-diplexing multiple-input multiple-output (SD-MIMO) antenna has been designed using a quarter-mode substrate integrated waveguide (SIW) cavity for wireless communication applications. This design employs two quarter-mode (QM) SIW cavities–one circular and –one rectangular in the self-diplexing element, which allows for high isolation (>20 dB) across the operating channels without the need for additional isolation networks. This feature provides a significant advantage over traditional designs that typically require extra isolation components to maintain high isolation between closely spaced antenna elements.
