Abstract :
A 9 X 13 printed microwave lens beam former was investigated numerically using MoM, and good performance was predicted across the quadruple band 6 GHz - 25 GHz. TTD behavior across entire band was achieved by array factor comparisons, with good beam quality demonstrations. Future work on this lens will involve the power efficiency study and prototype measurement validations.
