| 摘要 |
An antenna design, having two symmetrical phased array blade antenna elements which provide improved lateral target coverage with an increased effective radiated power and exhibits smooth null-free bi-directional antenna patterns. Each blade antenna element is coupled to a 180 degrees hybrid divider/combiner by a semi-rigid RF cable. Each blade antenna element is also connected to a sub-resonant choke balun for improved impedance matching and resultant distortion-less antenna patterns.
