BROADBAND CONTINUOUSLY FLARED NOTCH PHASE-ARRAY RADIATING ELEMENT WITH CONTROLLED RETURN LOSS CONTOUR

摘要

A flared notch radiator (11) is disclosed. The radiator (11) comprises a first planar metallic conductor (13) having a first contoured edge (15a) extending from a feed line C and a second planar metallic conductor (13') co-planar with the first planar metallic conductor (13) and having a second contoured edge (15b) adjacent to the first contoured edge (15a) and extending from the feed line (17). The contoured edges (15a, 15b) diverge from each other with distance h from the feed line (17) and are shaped to provide a high-pass Tchebyscheff-like reflection coefficient versus frequency characteristic.
