Description

The invention relates to the field of transceiver antenna arrays for communication repeaters operating on the inclined and circular polarization of electromagnetic waves, multifunctional hardware and software systems, unmanned aerial information systems, communication relays of dispatch centers [1-4].

An analogue of the claimed device is an antenna relay device that receives and transmits a signal when measuring the secondary radiation patterns of the antennas. The device represents a transceiver antenna, consisting of a pyramidal horn connected to a short-circuited waveguide fact, in which an amplitude-phase modulator is installed (copyright certificate No. 315128 from 1970, IPC G01R 29/10, Barenova I.V., Varshavchik M.L. , Kobak V.O.).

The disadvantage of the analogue is the narrow sector of working angles Δϕ, where ϕ is the spatial angle (for example, the azimuth angle).

The closest analogue (prototype) of the claimed device is a Van-Atta electrodynamic antenna reflector, consisting of N-nap waveguide antennas in the form of linear vibrators or waveguides connected by matched paths of the same electric length (US patent No. 2908002, class. 343-776 from 1955 )

The prototype has a narrow backscatter pattern, i.e. less than or equal to 80 ° (Δϕ≤80 °), where ϕ is the azimuth angle coinciding with the plane of the array of antenna re-emitters.

The aim of the invention is to provide a transceiver antenna array having a wider backscatter pattern. The inventive device allows to solve the following tasks:

- create a re-emitted communication signal in a wide sector of space angles to a value two times wider than the prototype;

- use one of the claimed device instead of two prototypes;

- reduce the overall dimensions of the communication relay.
