dual band transmitarrays with dual linear polarization at ka band
IEEE Transactions on Antennas and Propagation, 2017Co-Authors: K. Pham, R. Sauleau, Erwan Fourn, F. Diaby, A. Clemente, L. DussoptAbstract:Dual-band transmitarray antennas are demonstrated at Ka-Band with the capability of forming independent linearly polarized beams with a given polarization in each frequency band, while sharing the same radiating aperture. The proposed three-layer unit-cell is based on identical narrow microstrip patches printed on both receiving and transmitting layers and connected by a metallized via hole. The metal layers are printed on two identical substrates bonded with a thin film, and the designed unit-cell exhibits a 180° phase resolution (i.e., 1-b phase quantization). The dual-band dual-polarized property of the transmitarray is achieved by interleaving unit-cells operating in the down-link and up-link frequency bands. Four different prototypes are characterized to demonstrate the relevance of the proposed concepts. A good agreement is obtained between the radiation patterns, gain curves, and cross-polarization levels measured and computed in both frequency bands and polarizations.

Dual-band dual-polarized transmitarrays at Ka-Band
2017Co-Authors: K. Pham, R. Sauleau, Erwan Fourn, F. Diaby, A. Clemente, L. DussoptAbstract:Transmitarray antennas with dual-band and dual-polarization capabilities are studied here numerically. The antennas are designed based on linearly-polarized unit-cells working at Ka-Band for satellite applications. The unit-cells include two printed patches and a connecting via; a 180° phase shift is obtained by rotating one of the patches. The dual-band property is achieved by interleaving unit-cells dedicated to each band, and two different polarizations in each band. The numerical results demonstrate the working principles of dual-band dual-polarized transmitarrays. © 2017 Euraap.
