abstract

  • This work presents a wideband, reconfigurable transmitarray antenna (TA) unit cell (UC) design that supports dual-linear polarization. Namely, a novel TA UC is proposed, inspired by the magneto-electric dipole (MED) element, that achieves a 46% fractional bandwidth (BW). This UC utilizes a central via that is appropriately designed to allow the easy integration of the required PIN diodes, and enable 1-bit phase modulation (0° and 180°) between the transmitting and receiving elements. In addition, due to its design simplicity, our element is at least 4 times smaller compared to state-of-the-art MED elements. Notably, the small size and small number of vias of our element enable us to incorporate two orthogonal elements in a single TA UC so that two polarizations can be supported. The wideband performance of our proposed UC in the Ku band is demonstrated using simulation analysis in ANSYS HFSS.
