A novel dual-band transmitarray (TA) unit cell based on the Substrate Integrated Waveguide (SIW) technology is proposed in this article. The TA cell provides orthogonal linear polarizations for the two frequency bands while sharing the same radiating aperture. A dual-band, single-layer, frequency-selective surface (FSS) that generates a wave rotated of 90° to the incident one in one of the two bands, maintaining unchanged the polarization in the other is used. For each band, the proposed element and its mirror image can provide 0° and 180° phase shifts with 1-bit phase quantization. The proposed element can be easily fabricated as a single layer PCB with a standard manufacturing process.

Abstract
A novel dual-band transmitarray (TA) unit cell based on the Substrate Integrated Waveguide (SIW) technology is proposed in this article. The TA cell provides orthogonal linear polarizations for the two frequency bands while sharing the same radiating aperture. A dual-band, single-layer, frequency-selective surface (FSS) that generates a wave rotated of 90° to the incident one in one of the two bands, maintaining unchanged the polarization in the other is used. For each band, the proposed element and its mirror image can provide 0° and 180° phase shifts with 1-bit phase quantization. The proposed element can be easily fabricated as a single layer PCB with a standard manufacturing process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
