1-bit reconfigurable unit-cell based on PIN diodes for transmit-array applications in X-band

Abstract : An electronically reconfigurable unit-cell with 1-bit phase quantization (0°/180°) is proposed for X-band linear polarization transmit-arrays. It consists of two rectangular patch antennas loaded by U-and O-slots and connected by a metallized via hole. The transmission phase is controlled using two PIN diode switches integrated in the O-slot. An equivalent lumpedelement circuit model is implemented and compared successfully to full-wave simulations. The numerical results are validated experimentally using an ad-hoc waveguide simulator. The prototype exhibits low insertion loss (1.8 dB) with the same level for both phase states, a broad 3-dB transmission bandwidth (14.7%), a 1-dB compression point of 13-15 dBm and a gain of 5 dBi at 9.75 GHz. The performance and simplicity of the proposed unit-cell make it attractive to build electronically steerable transmit-arrays in X-band.
