研究目的
To propose a triple-resonance substrate integrated waveguide (SIW) cavity-backed slot antenna using two cavity resonators for millimeter-wave applications, addressing the narrow bandwidth issue of conventional SIW cavity-backed slot antennas.
研究成果
The proposed triple-resonance cavity-backed slot antenna successfully operates at 28 GHz, demonstrating a method to enhance bandwidth for millimeter-wave applications by utilizing cavity resonators. The similarity in radiation patterns at the three resonance frequencies confirms the design's effectiveness.
