M.E.C.'s X390-638 is an X-band, 16-element waveguide slot array antenna possessing a high power handling capability. This lightweight, low-profile antenna provides a directional beam with high efficiency and is suitable for a variety multipurpose radar applications. IEEE Xplore: IEEE Transactions on Antennas and Propagation - ( ) The first antenna based on substrate integrated gap waveguide (SIGW) is presented. Using two contacted metal strips to build the required conducting ridge, the SIGW addresses the defects inherent in the printed gap waveguide at millimeterwave frequencies. Investigation and Design of a Slotted Waveguide Antenna with ...

Millimeter Wave Wideband High Gain Antenna Based on Gap
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. Figure 1.
