Title
(EN) Flat slot array
Abstract
(EN)
A flat slot array comprising a number of waveguiding slot-type radiators (1) with a wide rear wall and with wide face walls (5a), which are provided, respectively, with exciting communication slots and with radiating slots (8) and which are located, respectively, in two parallel planes, and further comprising a waveguiding feeder network consisting of waveguiding power distributors and feeding waveguides whose channels are connected to the exciting communication slots. The waveguiding slot-type radiators (1) consist of strip line waveguides (1a) comprising a common dielectric sublayer (2) whose reverse side is covered with a metallized layer which serves as the wide common rear wall of the waveguiding slot-type radiators (1) each wide face wall (5a) of which is a striped line (5) consisting of alternating narrow and wide sections (6, 7) and located on the face side (4) of the dielectric sublayer (2).
