2-bit reconfigurable unit-cell and electronically steerable transmitarray at Ka-band

Abstract

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 across the TA aperture. The prototype demonstrates experimentally pencil beam scanning over a 120° × 120° window, a maximum gain at broadside of 19.8 dBi, and a 3 dB fractional bandwidth of 16.2%.
