  • Integrated microstrip helmet antenna system
    Patent number: 5886667
    Abstract: An integrated helmet and omnidirectional microstrip antenna system comprising a ballistic helmet constructed of rigid non-metallic material with a sheet of dielectric material as the top layer thereof and an omnidirectional microstrip antenna system having one or more antenna radiator elements affixed to the top surface of the dielectric sheet. The antenna radiator elements are circularly polarized by a microstrip feed network designed to provide circular polarization of a desired sense. A conductive layer of metallic material bonded to the underside of said dielectric sheet and integrated in the helmet structure serves as the electrical ground for the antenna.
