Solution Overview

Problem

Existing microwave weapons lack flexibility in emitting waves with multiple polarizations and directions, requiring multiple antennas and complex integration for target tracking, which complicates system implementation and processing of information from separate reception channels.

Innovation Solution

A method and antenna design that uses out-of-phase elementary antennas to emit coherent waves in multiple directions with opposite polarizations, allowing for simultaneous transmission in two distinct directions with the same frequency spectrum and phase, minimizing interference and enabling flexible orientation of coherent waves.

AI summary

The method involves determining a set of amplitude values (340) of a set of components, and providing a signal that is electronically processed. A value of an angle of a plane is calculated (350) from the amplitude values of each of the set of components. A set of electromagnetic waves emitted by the antenna network is phase shifted at an angle of 90 degrees with regard to each other. A set of elementary antennas or radial line antenna is provided in an antenna network, where the antennas are able to be rotated mechanically. An independent claim is also included for an antenna network.
