In this paper, 1-bit dual-polarized ultra-thin lens antennas based on Huygens' principle are presented. By tuning the transmission phase compensation in different states, the design and measurement of various single-beam patterns are achieved. The results show that the proposed antenna performs well in transmission within a specific frequency range.
In this paper 1-bit dual-polarized ultra-thin lens antennas are presented based on Huygens' principle. The unit cell provides two-state transmission phase compensation for dual-polarized waves. By tuning state 0 away from resonance and state 1 near Huygens' resonance, the 180' transmission phase difference between the two states is achieved. In the frequency range of 27.5-28.5 GHz, the transmission phase difference between the two states of the unit cell is 180 degrees +/- 20 degrees, and the transmission amplitude is greater than -2 dB. Using the proposed unit cell, three ultrathin 1-bit Huygens' metasurface antennas comprising 33 x 33 unit cells with single beams pointing separately at 0 degrees, 15 degrees, and 30 degrees are designed, fabricated and measured. Simulated and measured results show that the proposed 1-bit transmitarray antenna can achieve single-beam patterns, which is useful for the development of reconfigurable transmission and digital metasurface antennas in the future.
