  • Strip antenna with polarization control
    Patent number: 4454514
    Abstract: A linear polarization strip antenna which comprises a dielectric substrate whose backside is fitted with a conductive ground film, a power supply strip line which is formed of a conductive film and on the surface of the dielectric substrate, and a linear polarization radiation element. The strip line and radiation element are electromagnetically coupled together. A diode is connected between a top end of the strip line and a ground terminal. The top end of the strip line is selectively set at an open or grounded state according to the conductive state of the diode to vary the mode of electromagnetic coupling between the strip line and radiation element, thereby changing the direction in which the radiated electromagnetic wave is polarized.
