Advanced Antenna System Active Impedance Load Mitigation
This abstract first appeared for US patent application 20240421880 titled 'Advanced Antenna System Active Impedance Load Mitigation
Original Abstract Submitted
in an advanced antenna system, a desired power amplifier, pa, load distribution, which counters the mismatch of active impedance load, is achieved by altering the lengths of routing traces connecting pa outputs and corresponding antenna elements/subarrays. the combined output performance in the beam during active impedance load is then restored to the matched condition performance. this can be visualized as distributing the load impedance more evenlyâideally, on a circleâon a smith chart.
