RESONANCE SLOTTED WAVEGUIDE ANTENNA Russian patent published in 2014 - IPC H01Q13/10 

FIELD: radio engineering, communication.

SUBSTANCE: waveguide line, on one wall of which there are radiating elements and at the end of which there is a tuning element, includes phase-shifting devices mounted between radiating elements and between a radiating element and the tuning element, and communication elements connected to the waveguide, wherein the phase-shifting devices change the phase of the transmitted microwave signal in a wide range depending on its power level.

EFFECT: wide operating frequency range without deterioration of the directivity index and matching the antenna while maintaining the direction of the main directional lobe, as well as low cost and high technological effectiveness.
