摘要
The folded-monopole whip antenna is for a portable wireless communication device having a portable housing and wireless communication circuitry carried thereby. The antenna includes a flexible antenna element extending outwardly from the housing and having a proximal end for coupling to the wireless communication circuitry and having a distal end spaced from the proximal end. The flexible antenna element may have first and second flexible elongate legs or whips extending parallel to one another. The first flexible elongate leg may have a proximal end defining a first antenna feedpoint to be coupled to the wireless communication circuitry, and the second flexible elongate leg may have a proximal end defining a second antenna feedpoint to be coupled to the portable housing. The first and second flexible elongate legs may have distal ends electrically coupled to one another. A dielectric layer may be fastened between the first and second flexible elongate legs. The folded-monopole whip antenna may provide a tactical military antenna for manpack radio requirements, with greater gain, smaller size and reduced visability at HF and VHF frequencies. It may use capacitor only matching across broad tunable bandwidths, and an elevated feedpoint for increased efficiency and RF safety.
