Abstract
A low band radiator for a dual band antenna having a low band and a high band. The radiator includes a dipole arm having a center conductor and at least one RF choke including at least one partial box section closed at one end and open at the other end and having two opposing sides, a bottom and an open top. The closed end is shorted to the center conductor and the partial box section is quasi-coaxial with center conductor. The choke is resonant near the frequency of the high band of the antenna. The dipole arm may include a plurality of the partial box sections with a gap between each section to form a plurality of RF chokes. The dipole arm may be fabricated as a single die cast metal piece or as a plastic injection molded piece plated with conductive material.
