ABSTRACT:
An antenna having an impedance matching section for attaching to a sheet or a garment. The antenna has a first, a second, and a third leaky substantially coaxial conductor. The first and the third coaxial conductors have an electrically conductive layer placed on the dielectric in a double helix. The second coaxial conductor has an electrically conductive layer placed on the dielectric in a single helix. The first coaxial conductor is coupled to the second coaxial conductor, the second coaxial conductor is coupled to the third coaxial conductor; and the third coaxial conductor is coupled in use to a first termination impedance. Methods to make the foregoing structures are also described.
