Abstract
The present invention relates to a cylindrical electronically scanned antenna. The antenna has: a set of radiating guides () arranged in cylinder form for, producing the antenna beam (); An array () of 3 dB couplers is arranged in waveguide form. The inputs of the array are lit by a set of microwave feeds (). The output of each coupler is coupled to the input of a radiating guide (). An array of pairs of phase-shifting cells is, each coupled to a 3 dB coupler. An incoming wave from the microwave feeds () is phase-shifted by a controllable phase shift Δφ. The angular offset of the antenna beam () is dependent on this phase shift Δφ. The invention is typically applicable for equipping masts, in particular on ships.
