Abstract
In this paper, a compact substrate integrated waveguide (SIW) fed dielectric antenna with equivalently tapered E-plane profile is proposed and investigated. Firstly, transition from SIW to broadwall-detached SIW (DSIW) is analyzed, which provides basis for designing a compact SIW-fed dielectric antenna. Secondly, in order to realize an effective radiation structure while keeping geometrical size unchanged, a gradually tapered profile in E-plane is realized through perforating air-vias with different diameters into the DSIW. Effect of transition stage(s) is compared to validate the function of equivalently tapered profile. Results indicate the proposed antenna operates with 27.7 % fractional bandwidth ranging from 20.2 GHz to 26.7 GHz. Moreover, stable end-fire radiation patterns can be observed in the whole operating band. Above all, this antenna shows similarity with E-plane waveguide horn antenna but maintains advantage of planar configuration.
