Introduction An increasing demand of applications at the mil-limeter- and submillimeter-wave bands is expect-ed to be imminent. There are already some ap- 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 Waveguides - Springer waveguide and ridge gap waveguide. One of the approaches is the spectral domain approach in which ... Section “Low-Loss Antennas Based on Gap Waveguide Technology” presents different types of ... In the context of high-efficiency waveguide slot array antennas, this electrical contact issue is a very important factor for good electrical ...

Antennas: The Slotted Waveguide Antenna An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna. As in the cavity-backed slot antenna, each slot could be independently fed with a voltage source across the slot. However, (especially for large arrays) this would be very difficult to ... PARAMETRIC STUDY OF WAVEGUIDE SLOTS AND ANALYSIS OF RADIATION ... PARAMETRIC STUDY OF WAVEGUIDE SLOTS AND ANALYSIS OF RADIATION PATTERN FOR THE DESIGN OF WAVEGUIDE ARRAY ANTENNA M. Mondal Kalpana Chwala Space Technology Cell Department of E & ECE, IIT KGP Kharagpur-2, India A. Chakrabarty DEAN (Continuing Education) Electronics Electrical Communication Engg. IIT Kharagpur, India Antennas: The Slotted Waveguide Antenna (Planar Array of Slots) The problem arises because the physical dimensions along the E-plane is much shorter than that along the H-plane (the slotted waveguide is long but thin). In general, a longer antenna (or longer array) produces a narrower beam. This problem can be circumvented by arranging slotted waveguides in parallel, as shown in Figure 1.
