Abstract 

    A large frequency interval dual-band high-gain slot array antenna based on SIW (substrate integrated waveguide) for simultaneous microwave and millimeter wave application is proposed in this paper. The designed antenna consists of 2 arrays working on 9.86 GHz ~ 10.2 GHz and 25.9 GHz ~ 39.53 GHz, which can meet demand on X- and Ka-band, respectively. Two substrates sandwiched between three layers of metal are employed, and all slots are located on the second metal layer. A slot along the mid line manages to convert the electromagnetic energy between slotline and the higher order mode SIW. The antenna was fabricated and measured in the experiment. The results demonstrated |S1,1|<-10 dB from 9.76GHz~10.25GHz and 26.7GHz~40GHz, which cover the whole Ka-band. And the gain was up to 10.9 dBi (10 GHz) and 9.05 dBi (37 GHz), which coincide with the one simulated and modified with CST Microwave Studio®. The antenna applied to both microwave and millimeter wave system shows promised prospects.
