Design and Verification of a Miniaturized Multifunctional Transmitarray Unit Cell for the S-Band
In this paper, a miniaturized multifunctional unit cell structure of a transmitarray operating at S-band and its verification method using a waveguide structure is presented. The unit cell of a multifunctional transmitarray antenna is a critical component because it controls the phase and polarization of an incident wave. The proposed unit cell consists of three main parts: an Rx antenna, a Tx antenna, and a control circuit for phase and polarization. The performance of the designed unit cell is verified by a rectangular waveguide structure. The waveguide structure feeds an electromagnetic wave propagating in a TE10 mode to a 1 × 2 unit cell array to verify polarization and phase shifting capability of the unit cell. The phase shifting and polarization conversion capabilities of the proposed unit cell are directly measured by the radiation patterns and polarization of the transmitted wave.
