Dual linearly polarized transmitarray antennas with wideband performance are investigated in X-band. Their designs are based on unit-cells with bandpass response. Their structures consist of three conducting layers printed on two identical dielectric substrates glued with a bonding film. Detailed experimental results demonstrate excellent polarization independence, with expected performance and properly preserved radiation characteristics for each polarization. The measured data are in excellent agreement with full-wave simulation results.
