By transferring the conventional waveguide resonant slot array antenna to the substrate integrated waveguide (SIW) structure, we could get the advantages of the resonant slot array antenna as well as the advantages of the SIW such as small size, low profile, low cost. In this letter, the design of a SIW resonant five-slot array antenna at Ku-band and its radiation patterns and impedance bandwidth are presented. |
