Phased-array receivers provide two major benefits over single-antenna receivers [1]. Their signal-to-noise ratio (SNR) doubles for each doubling in the number of elements, resulting in extended range. Secondly, interferers can be rejected in the spatial domain for increased link robustness. These arrays can be implemented by phase shifting and summing the signals from antenna elements with uniform spacing. For accurate interference rejection, a phase shifter with uniform phase steps and… CONTINUE READING
