A dual-polarized slotted-waveguide antenna based on gap waveguide technology
Paper in proceeding, 2017
Euraap.This paper describes a wide-band dual-polarized slotted-waveguide antenna working at V-band (57-66 GHz) based on Gap Waveguide concept. The antenna has three layers. The first one (feeding-layer 1) is practically identical to the second one (feeding-layer 2). This optimizes the design and facilitates manufacturing. The corporate-feeding networks on the two layers are rotated 90 degrees to each other to get the two orthogonal polarizations. Radiating elements are square apertures located on the top of the antenna. Simulated results show both impedance bandwidth and radiation pattern bandwidth greater than 15% for both polarizations.
