  • Phased array antenna for radio frequency identification
    Patent number: 5686928
    Abstract: A multi-element, H plane, phased, dipole array antenna has a high gain over a wide angle in azimuth and over a controlled sector in elevation. Two printed wiring boards feed and physically support the dipole antenna elements. The phase and spacing of the dipole elements establish the radiation elevation angle, and a planar metallic reflector, spaced on the order of a half wavelength of the RF signal from the dipole array, interacts with the dipole-element pattern, to provide the wide angle azimuth gain.
