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. Rotman lens with Ridge Gap Waveguide technology for ... In this paper, a Rotman lens with Ridge Gap Waveguide technology (RGW) is proposed as an alternative for beam scanning in millimeter wave applications. To facilitate the design and measurements, a first prototype at 38 GHz will be designed and built; afterwards a final device at 60 GHz will be designed.

Millimeter Wave Wideband High Gain Antenna Based on Gap ... We present a multi-layer fixed beam slot array antenna design based on ridge gap waveguide technology in this work. The designed antenna has good impedance bandwidth and also good radiation patterns over the band of interest at 60GHz. The main feature of the gap waveguide antennas is the flexibility in mechanical assembly which will allow low cost
microstrip-based ridge gap waveguide (GWG) technology is applied to feed the SIC subarrays. Furthermore, for measurement purposes, a wideband transition structure between rectangular waveguide (RWG) and GWG is designed. Measured results show that an 8×8 slot array with the transition achieves a maximum New waveguide technology for antennas and circuits Keywords Gap waveguides, metamaterial-based waveguides, hard surfaces, microwave circuits, millimeter-wave antennas, slot arrays, waveguide slot arrays. 1.
