Abstract. Investigation and design of two multimode printed antennas single and dual layered are considered. These antennas are intended for use in anti-jamming and direction finding systems. Proposed antennas are analyzed with help of an approximate resonator model. It is demonstrated numerically that these antennas may form radiation pattern with null in the required arbitrary direction for waves of both orthogonal polarizations. It is demonstrated with help of a numerical simulation that in the proposed antenna three dominant eigenmodes may be tuned to have identical resonance frequencies and Q-factors close to Q-factor of a conventional patch antenna. Application of three ports provides well matching and independent excitation of eigenmodes. Results of experimental investigation of dual layered printed antenna are presented.

Keywords: printed antenna, multimode antenna, anti-jamming, phase direction-finding.
