Broadband compact transducer of shelf type

Abstract: Simulation has been carried out and its results of calculation of the “shelf” type emitter have been presented. The design of this emitter consists of two metal disks mounted on supports, one of which is located on a dielectric substrate. The layout of the developed emitter is investigated. Measurements of KU, SWR, DN and CE of the manufactured model were carried out. The developed radiator is not inferior to the well-known analogues of emitter used as part of multibeam antennas in terms of REC, and also has advantages over them, namely a smaller vertical overall dimension, which is one of the most important criteria when choosing the type of radiator.

Keywords: microstrip radiator, shelf type radiator, compact radiator, multibeam antenna radiator
