A Sequential-Phase FEED Antenna Subarray Based ON Ridge GAP Waveguide
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. Long Slots Array Antenna Based on Ridge Gap Waveguide ... Long Slots Array Antenna Based on Ridge Gap Waveguide Technology Abstract: Ridge gap waveguide (RGW) technology is used in the design of a frequency scanning antenna with high gain and directivity. A Quasi-TEM horn with shaped ridge is designed as a guiding structure between two metallic surfaces. The waves are suppressed beyond the shaped ...
