A new design of the double dielectric resonator antenna (DRA) fed by a printed ridge gap waveguide for beam‐switching applications based on frequency selective surfaces (FSSs) is presented here. The dual‐sided printed FSS element works in its reflection mode and comprises a slotted square C‐shaped patch on the top layer and a square strip on the back plane. Therefore, the beam switching can be implemented by loading the proposed FSS array over and in the middle of DRAs. Loading the antenna with two layers of 3 × 3 FSS unit cells results in ±77° beam switching and a 3.16 dBi gain enhancement at 28 GHz. Simulation and measurements confirm the operation of the proposed antenna, with good matching and gain observed.
