Antennas

X-band Fan-Beam Slotted Waveguide Antenna
The antenna has been designed for the synthetic aperture radar (SAR) application. It radiates fan-like radiation pattern with specified beamwidth in principal planes in order to achieve optimal parameters for SAR resolution.

Ka-band Large-Aperture Slotted Waveguide Antenna
The antenna is intended for high-resolution radar application. The antenna contains of about 1500 radiating slots, which forms the fan-like radiation pattern in the broadside with low sidelobes.

V-band Horn with Flat-Topped Beam
The horn produces flat-topped radiation pattern in wide operating frequency band of about 10 percents. Its polarisation is linear with low level of cross-polarization.

Ka-band Cassegrain Antenna System
The 1m-aperture dual-reflector antenna of Cassegrain type is characterised by a high gain and low sidelobes along with a dual-polarisation mode capability.

Ku-band Circular Slotted Waveguide Antenna with Inclined Beam
A highly efficient, compact slotted waveguide antenna with circular aperture is designed for operation in Ku-band. The beam of this antenna is essentially inclined with respect to the antenna surface normal what has enabled to reduce dramatically the antenna radar visibility from the target direction.

Details


Ka-band Electrically Switchable Slotted Waveguide Antenna
The antenna system consists of four independent slotted waveguide sections together with a radar T/R-module. Each antenna section forms the radiation pattern with the beamwidth of 10° in the elevation plane and 2° in the azimuth plane.
