Abstract
In this study, we propose a multi-functional unit-cell that integrates reflectarray and linear polarizer functions together. The unit-cell is composed of multi-layer structure and depending on the polarization, it can perform as reflectarray or transmission type liner polarization converter. Our results demonstrate that in the reflection mode, the unit-cell shows high reflection magnitude around one and nearly full phase coverage of 310° at 14 GHz. In the transmission mode, the unit-cell functions as highly-efficient linear polarization converter with PCR more than 95% in the broad frequency range of 3 GHz to 14 GHz. Our results reveals that the proposed unit-cell is suitable for multi-functional applications such as bidirectional wireless Communication.
