Abstract :
A new dual polarization lens working at the frequency of 30GHz has been designed and simulated. The design of the unit cell is based on a structure of four stacked patches coupled by a symmetric cross that achieves a 360-degree phase-shift for both polarizations by varying a different dimension of the patches for each one. In this design, a quasi-independent relationship between both polarizations has been achieved. Hence, a simple synthesis algorithm to lower the dependence between them is used. Finally, in order to prove the good behavior of the system a lens with two different steering directions is designed and simulated showing good performance for both polarizations.
