A WIDEBAND SLOTTED WAVEGUIDE ANTENNA ARRAY FOR ... - jpier.org 3. ANTENNA SYNTHESIS Our design goal was to develop an X-band slotted waveguide antenna with a 4– £ 6– antenna beam and the relative operational bandwidth of about 15%. A rectangular array of radiating slots has been selected. The rectangular aperture is separable one [7], so it is possible to Design of Slotted Waveguide Antenna for Radar Applications ... Slotted waveguide antennas are mostly employed in Radar applications. This paper analysis the structure and design procedures of slotted antenna in the broad wall. This design specifications are chosen for high gain and mechanical robustness. The slotted waveguide antenna designed is a directional type antenna with gain of 16db.

I would guess that the walls of the odd structure on top of the above airplane contain a large slotted waveguide array, for scanning in the horizontal (azimuth) plane around the airplane. ... Design Principles. Antennas List.

A New Waveguide Slot Array Antenna with High Isolation and High ...

Slotted waveguide arrays consist of a number of slots cut into the walls of a waveguide forming an array with the slots acting as individual radiating elements. The specific design task here is a 10-element transversal slot array cut into the upper wide side of a WR-51 standard rectangular waveguide.

7.2.3 Waveguide slot array design A sketch of a waveguide slot antenna with the pertinent dimensions is shown in Figure 7-5. The first design consideration is that the slots be resonant so that they provide a resistive load to the (waveguide) transmission line.
