Combined identification friend or foe-radar antenna for ship, has dipoles with wires coiled in helix inside dielectric bushing sleeves, where step and diameter of helix and diameter of wires are chosen to be low
The antenna has dipoles arranged in front of a reflecting surface (1) of a radar antenna and having wires (40, 50) coiled in helix inside dielectric bushing sleeves (41, 51). The step and diameter of the helix as well as diameter of the wires are chosen to be low. The length of the wires is determined according to the helix and dielectric constant parameters and diameter of the sleeves.
