Abstract
An electronically scanned antenna working in a wide frequency band comprises at least: one reflector panel comprising an array of phase-shifters cells; one slotted waveguide illuminating the reflector panel by a microwave having a variable frequency f. The deviation Δθof the direction of the wave emitted by the slotted waveguide, as a function of the frequency variations, countering the variation Δθof the aiming direction of the wave reflected by the reflector panel. The disclosed antenna can be used especially in applications requiring compact or low-cost antennas.
