Abstract
A conductive element with a primary branch and a secondary branch are separated by a bend segment and the signal and ground feeds are positioned adjacent each other on a common portion of the conductive element. The frequencies in the high band may be at least about twice that of the frequencies in the low band. The branches and bend segment are constructed such that the primary branch radiates at both high and low band operation. The two branches combine to form a more efficient high band radiator.
