The generalized model of radiation field of frequency independent antennas on the basis of spiral structures has been developed. Elliptical and circular helix, hemisphere, flat spiral and zigzag antennas have been investigated and recommended for real application. Experimental models have been developed the prescribed antennas with optimized parameters. Th obtained results can be used on land and space communication systems.
