Abstract
A highly selective, multiband, passive unit cell is introduced. The device is realized by incorporating a high impedance, periodic, patterned metal surface between two layers of dielectric in-between two parallel metal planes. The patterned surface is connected to the metal planes through metalized vias and through metal pins. The properties of the device have been assessed by numerically computing the dispersion diagram using a commercial software. The narrow pass-bands present in the microwave frequency range makes the structure well-suited for filters intended for direct incorporation in antenna feeders in view of wireless applications. Q-factor as high as 300 can be achieved.
