2-Bit Reconfigurable Unit-Cell and Electronically Steerable Transmitarray at Ka-Band

This communication presents the design, optimization, fabrication, and characterization of an electronically steerable transmitarray (TA) with 2 bits of phase quantization per unit cell. The proposed TA operates in linear polarization at Ka-band and is composed of 14 × 14 reconfigurable unit-cells. Four p-i-n diodes are integrated on each unit-cell to control the radiated field phase distribution ...
