Abstract

A simple structure of reconfigurable unit cell is proposed for 1-bit transmitarrays in the C-band. It consists of two square ring patches capacitively coupled to U-shaped microstrip resonators, all implemented on a 5-layer printed circuit board. The resonators on one side of the unit cell are connected to the resonators on the other side through vias. The structure can operate on dual linear polarized waves and features minimum number of vias, low insertion loss and a 2.8% fractional bandwidth. The change of the phase state between 0° and 180° is implemented with PIN diode switches. The unit cell simulation results are validated by measurements of a stand-alone unit cell in a rectangular waveguide. In both phase states, the transmission and reflection coefficients have very similar values with the minimum insertion loss of 1.7 dB and 1.9 dB at 5.9 GHz in the phase states of 180° and 0°, respectively. Application of the proposed unit cell for 1-bit reconfigurable transmitarrays is discussed and the effects of the phase quantization are evaluated numerically
