Dual-polarized compact low-profile antenna for airborne synthetic aperture radar (SAR) applications was investigated. The distributed discrete capacitive loads are used to extend bandwidth of cylindrical antenna. The proposed antenna configuration has an 57% bandwidth at VSWR<2.5 and isolation over than 30 dB. Details of antenna design and experimental results are presented.
