Abstract :
A method for raising the crossover level of dual-beam parabolic antennas is shown. Controlled coupling between the primary radiators, with the input ports almost decoupled simultaneously, can be applied to front-fed linearly polarised parabolic antennas of about 10° beamwidth. Mention is also made of a second method with lossy directional couplers.
