PROJECT TITLE :

1-Bit Reconfigurable Unit Cell for Ka-Band Transmitarrays

ABSTRACT:

This letter presents an electronically reconfigurable, linearly polarized unit cell for transmitarray applications in Ka-band. A 1-bit phase resolution (namely with two phase states zero ° and a hundred and eighty °) is obtained using two p-i-n diodes mounted on a slot-loaded patch antenna. The planning, realization, and experimental characterization in a standard waveguide simulator are reported. The measured insertion losses only reach 1.09 and one.twenty nine dB for the two-phase states, respectively, with a 3-dB transmission bandwidth of concerning eleven.2%.
