Design, manufacture, and experimentally characterize an electronically reconfigurable 1-bit unit cell for Ka-band transmitarray antennas.
Engineered a slot-loaded patch antenna integrated with two surface-mounted p-i-n diodes to achieve 0° and 180° phase states.
Conducted experimental validation and RF characterization inside a standard Ka-band waveguide simulator.
Achieved measured insertion losses of 1.09 dB and 1.29 dB for the 0° and 180° phase states, respectively.
Obtained a 3-dB transmission bandwidth of approximately 11.2% around the operational frequency.
