Broad-band antenna having folded dipoles with hairpin transformers

Abstract: A broad-band antenna characterized by having a folded dipole that includes first and second open center portions with a broadband transformer element spanning one of said open center portions while transmission line feed points are located at the opposed sides of the other open center portion, with this arrangement permitting the transformer element to electrically lengthen the antenna into half-wave folded dipole antenna for the reception of low-band signals while also simultaneously electrically opening the antenna into a full-wave dipole antenna for high-band reception. By the use of a single antenna to receive two bands from a broad-band spectrum, size and weight are reduced while simultaneously achieving a greater gain in decibels than would otherwise occur absent the use of the arrangement above-described.
