FIELD: radio engineering, communication.
SUBSTANCE: invention relates to broadband two-polarisation antenna intended to be used as a separate device or as part of phased antenna arrays. The antenna design creates an orthogonal basis, which allows emission of electromagnetic waves with different types of polarisation. The antenna includes feeders, a conducting screen and an emitting element in the form of a four-beam star, which is located above it. Star beams are smoothly bent in the screen direction and connected with their apexes to the feeders. Smooth change of shape and height of the beams above the screen allows coordinating the feeders and free space in wide frequency range. The antenna has a simple design, small dimensions and weight.
EFFECT: good coordination of feeders.
