Dual-Band Antenna Made of Slow-Wave Substrate Integrated Waveguide

In this paper, a dual-band and broadband slow-wave substrate integrated waveguide (SW-SIW) structure antenna is designed and analyzed. The geometry of the proposed antenna consists of the SIW cavity structure and fractional slots,including one ring slot and three rectangular slots etched on the radiation patch. The ring slot and rectangular slots are etched on the radiation patch to achieve the dual-band, broadband and slow wave characteristics. The simulated results show that the -10 dB impedance bandwidth of the presented antenna is 14.2% (12.04 GHz-13.88 GHz) and 3.25% (14.15 GHz-14.58 GHz). The peak gains of the dual-band antenna are 8.38 dBi and 8.18 dBi. In conclusion, the study indicates that the proposed antenna has dual-band, broadband, high gain, and miniaturized performances. Further work will be devoted to prototype fabrication and optimization.
