SLOTTED WAVEGUIDE ANTENNA ARRAY Russian patent published in 2005 - IPC

FIELD: microwave engineering; slotted waveguide antenna arrays for radar systems of flying vehicles.

SUBSTANCE: proposed low-silhouette slotted waveguide antenna array enabling use of group method for manufacturing its components is, essentially, multilayer waveguide system that has radiating antenna array divided into a number of subarrays and power distribution circuit. Radiating elements of slotted waveguide antenna array are longitudinal slots in wide walls of waveguides. Multilayer waveguide system is, essentially, multilayer structure assembled of alternating interconnected thin conducting plates and conducting bases, the latter being provided with through holes forming waveguide channels, and plates forming wide walls of waveguides are provided with through holes of radiating or coupling elements, or power supply elements.

EFFECT: facilitated manufacture, enhanced manufacturing and assembling precision, strength, and yield.
