Abstract :
Results of theoretical analysis and experiments for separate parts and elements of a flat multilayer microstrip phased array antenna based on phase-shifters with ferroelectric varactors are presented. Mutual coupling and crosspolarization phenomena between radiator elements of two-layer patch aperture have been theoretically and experimentally studied. Calculated and measured data on the phase-shifter parameters are presented.
