Airborne A/C and space earth survey systems use antenna synthetic aperture radars that operate in several frequency bands, including P band (70 cm) of wave lengths. The height of antenna profile is one of the important parameters both in aircraft and spaceborne radars. It is important to maintain the carrier aerodynamics in the aircraft equipment, and in the spaceborne equipment - for close-together arrangement inside radome in the launch of space vehicle on orbit. The solution of the whole number of practical tasks requires the use of low-profile dual polarized antenna radiators with high decoupling in polarization. This task can be solved using structures with high impedance surface properties - artificial magnetic conductor (AMC) and electromagnetic bandgap structure (EBG). The use of artificial surface with high surface impedance properties made it possible to design low profile antenna system with suffi-ciently high decoupling among polarization channels. The developed antenna has low VSWR values (no more than 1,6) and decoupling among polarization channels (no more than −30 dB) in operational frequency band (435±30 MHz) at height 38 mm (0,05 λ0), while in traditional solution as a dipole above metallic surface the height would be 172 mm (0,25 λ0). For verifying the results a radiator was fabricated and tested. The measured characteristics have good coincidence with the simulation characteristic.
