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. E-band 3-D Metal Printed Wideband Planar Horn Array Antenna The gap wave-guide technology presents a solution to the existing problem of good electrical contact among the different antenna parts. Thus the gap waveguide based antennas have much simpler mechanical assembly at high frequency. In this paper, we present the ridge gap waveguide based planar horn array with wide impedance bandwidth and high ... Wideband Coaxial to Ridge Gap Waveguide Transition ... Recently, ridge gap waveguides are considered as guiding structures in high-frequency applications. One of the major problems facing this guiding structure is the limited ability of using all the possible bandwidths due to the limited bandwidth of the transition to the coaxial lines. Here, a review of the different excitation techniques associated with this guiding structure is presented.
Gap waveguide technology is based on parallel-plate waveguide configuration and using a periodic array of electromagnetic bandgap structure to control the direction of propagation. ...
