Analysis of an off-broadside zero beam-squinting leaky-wave antenna using metamaterials
(Institute of Electrical and Electronics Engineers Inc., 2016)It is shown that zero beam-squinting can be achieved in both series fed antenna arrays and leaky-wave antennas by employing two parallel-connected metamaterial transmission lines with equal positive group delays, but with ...
