Impact of phase compensation method on transmitarray performance

Abstract : The impact of the phase compensation method on transmitarray (TA) performance is studied here in terms of directivity, gain, aperture efficiency, and beam scanning capability. The analysis has been done by considering generic TAs based on ideal unit-cells and illuminated by an ideal focal source with a gain of 10-dBi and 100% of efficiency. The phase compensation on the array aperture can be implemented using two different methods, namely constant phase-shift and True Time Delay (TTD). The numerical results show that TTD compensation allows increasing the TA bandwidth and reducing beam squint as compared to constant phase-shift compensation. © 2017 Euraap.
