Dual-polarized radiator with high isolation for phased antenna arrays

We propose the small-size dual-polarized radiator with high isolation. It is intended for use in a phased array with a wide scanning sector. Such radiator can also be used to construct an active phased array for satellite radars with synthesized aperture. The geometrical parameters of the radiator and the four-element module, as well as their general antenna characteristics have been optimized. The optimization results for the main characteristics of the radiator and the four-element module (VSWR, coefficient of isolation, directivity, radiation pattern shape) have been shown in the 6% frequency band, operating in the X-range.
