The broadband compact antenna with the radiation field of circular polarization

In the report possibility of expansion of a strip of the coordination is discussed at build-up of antenna system on the basis of flat spiral structures at the expense of magnification of initial radius of spirals and application of conical transition on an inlet of radiators. The law of winding of a conductor in conical transition at which in a wide frequency band the qualitative coordination of the antenna without use matched devices and stable radiation characteristics of the antenna is provided is offered.
