This paper is devoted to designing and manufacturing the compact wideband reflector antenna with the monopole sub-reflector. Based on the computation modeling and experimental investigations the effect of separate elements of the proposed antenna on the radiation characteristics is studied. The regularities of radiation pattern shape are determined. Finally, the experimental antenna prototype is described, as well as the input antenna characteristics, near-field distributions and radiation pattern are analyzed.
