  • Elongate radiator conformal antenna for portable communication devices
    Patent number: 6292144
    Abstract: An elongate radiator conformal antenna for portable communication devices is conformed on or in dielectric. The antenna of the present invention is a conformal antenna having an elongate radiator element grounded to a ground plane generally opposite the elongate radiator element, and driven by a feed connected to the elongate radiator element at a point between its connection to the ground plane and its open end. The elongate radiator element and ground plane are conformed with dielectric which, due to its wavelength shortening effect, reduces the required length of the elongate radiator element to less than a quarter wavelength. The dielectric material with which the antenna is conformed and any additional dielectric material between the elongate radiator element and the ground plane is preferably high permittivity and low loss tangent material.
