Phased array blade antenna assembly

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.
