Fig. 3. Antenna gain as a function of frequency. microstrip gap waveguide to a microstrip line is required. In Planar slot‐array antenna fed by an oversized quasi‐TEM
wave antenna based on a periodic structure and connecting the antenna to the standard 50 Ω equipment. For achieving this purpose a quasi-TEM transition and a transition from microstrip to substrate integrated ridge gap waveguide has been designed. In addition, the slots of the
of two analytical approaches used so far in the prediction of propagation performance of groove gap waveguide and ridge gap waveguide. One of the approaches is the spectral domain approach in which Green’s functions of the considered structure are determined. On the other hand, in the second approach, IEEE Xplore: IEEE Transactions on Antennas and Propagation - ( ) A novel fully on-chip antenna based on a metasurface fabricated in a 180-nm BiCMOS process is presented. Inspired by the concept of high impedance surface (HIS), this metasurface is not used as a reflector below an antenna as commonly done. Instead, it is used as a radiator by itself. An antenna design in gap waveguide using CST - Semantic Scholar These papers present the propose of a double layer slot array antenna at microwave frequency range K-band in gap waveguide technology. Gap waveguide technology is a solution to reduce the performance gap between planar transmission lines and metal waveguide in terms of loss, manufacturing flexibility and cost.

A slot array waveguide antenna was designed using ridges on its narrow wall and nine radiation elements having a frequency of 5 GHz by applied the normalized conductance of each radiating slot. It is shown that good performance can be achieved even for concave and convex ridges in waveguide.
