Abstract

The paper brings results of numerical studies of four different concepts of filtering antennas: the dipole array with serial feeding, the patch array fed by the Substrate Integrated Waveguide (SIW) resonators, the low-pass filter antenna with the Defected Ground Structure (DGS), and the patch array fed by apertures. Filtering antennas are mutually compared from the viewpoint of frequency response of gain in the main lobe direction and impedance matching. Parameters of selected filtering antennas are verified experimentally.
