In this paper, a design of Substrate Integrated Waveguide (SIW) cavity backed slot antenna for polarization diversity application is presented. The proposed design uses a pair of slots placed at right angle with respect to each other at the top metallic plate of the cavity to generate two linear orthogonally polarized radiation pattern at same frequency to implement polarization diversity technique...
In this paper, a novel design of substrate integrated waveguide (SIW) cavity backed slot antenna for dual frequency and broadband application is demonstrated. In the proposed design, a parasitic slot is placed along with the conventional central slot at the top metallic plate of the cavity to generate dual frequency resonances at 10.08 GHz and 11.96 GHz. The central slot is placed at the center of...
In this paper, a design of planar, compact dual frequency slot array antenna is implemented using substrate integrated waveguide (SIW) cavity backed slot antenna as array element. The proposed design uses a pair of slots placed at the top wall of the cavity to excite higher order hybrid mode along with conventional TE120 mode which helps to create dual resonances. A design of 1×4 array of the proposed...
In this paper, a dual-frequency substrate integrated waveguide (SIW) cavity backed slot antenna has been presented. The unique slot structure includes a pair of slot stubs connected at the center of the radiating slot which helps to create an additional hybrid mode resonance at the higher frequency end. As a result, the antenna resonates at two different frequencies 8.96 GHz and 15.84 GHz with a bandwidth...
