We propose a novel planar slot‐array antenna fed by a new guiding structure which forces a quasi‐TEM mode within an oversized rectangular waveguide. To achieve a quasi‐TEM mode throughout the waveguide a hard surface is placed on the bottom surface of the waveguide while the radiating slots are at the upper face.

In this paper, a high gain high efficiency 16×16- element slot antenna array is presented for 60 GHz applications. The antenna is designed based on gap waveguide technology. A corporate feed network is realized by a texture of pins and a guiding ridge in a bottom ... Ku band linear slot-array in ridge gapwaveguide technology Abstract A Ku band 4×1 linear slot array antenna design based on recently developed gap waveguide technology is presented. The complete antenna has been built using two parallel plates where the bottom metal plate has the guiding ridge and periodic pins and ... Micromachined ridge gap waveguide and resonator for millimeter-wave applications - ScienceDirect Two devices were fabricated: a ridge gap resonator and a ridge gap waveguide, both shown in Fig. 1. Both are based on the same basic idea, namely by having a Perfect Electric Conductor (PEC 3) surface parallel to an Artificial Magnetic Conductor (AMC 4) surface ...

Slot antenna in ridge gap waveguide technology
An example of a standing wave slotted waveguide antenna is given in [19], where a ridged waveguide is used to help extend the scanning an-gle of a frequency scanned antenna. This work done in [19] ties in very closely to what is done here, as the basic topology of the antenna is similar.
