Abstract

This paper proposes a novel 1-bit transmitarray for Ku-band applications, featuring wide bandwidth, compatibility with multiple polarizations, and simple structure. The design incorporates two units with a 180° transmission phase difference, realized using slotted circular patches. Due to the rotational symmetry of the circular patch, these units can receive and transmit electromagnetic waves with different polarizations without mechanical rotation. Both unit cells achieve a transmission coefficient higher than −1-dB within the frequency range of 11.7 - 20.5 GHz. Leveraging these high-performance unit cells, the transmitarray achieves a wide 3-dB gain bandwidth of 42.07%, a peak realized gain of 24.48 dBi/dBic, and a peak aperture efficiency of 28.4%. This advanced design significantly enhances the efficiency and effectiveness of satellite communication systems and other applications that require high-gain, wideband, and polarization-independent transmitarrays.
