In this contribution, we propose a new reconfigurable unit-cell design operating in circular polarization in Ka-band. Two p-i-n diodes are integrated in order to achieve a phase resolution of 1 bit (0°/180° are the possible phase states). An insertion loss of about 1 dB at 29 GHz with a 3-dB relative bandwidth of 14.5% has been numerically demonstrated. © 2016 IEEE.
