Abstract. Design, numerical simulation and experimental investigation of microwave printed antennas containing resonance radiator and non-radiating resonator are considered. It is shown that such antenna may be used as a second order filter. Specific features of such filter synthesis are analyzed. Several models of printed antenna are proposed: phenomenological model including a system of coupled resonators, phenomenological model on the base of a system of coupled transmission lines, electromagnetic model. Results of numerical calculations and experimental studies are presented.

 Keywords: antenna, printed antenna, antenna-filter.
