Abstract. Different types of radiators: sharp end of single-strip line (SSL), narrowed end of SSL, patch resonator were developed and investigated. The investigation of matching, polarization and directivity of radiation characteristics were conducted on the base of the Finite Element Method (FEM). It was shown that the patch resonator radiator is the best of them from the point of view of matching with SSL and has much more wide band of frequencies in comparison to the microstrip patch radiator. The results of the numeric research are well conjugated with the physical experiment.

Keywords: radiators, single-strip line (SSL), Finite Element Method (FEM).
