  • Bifilar helical antenna
    Patent number: 7113148
    Abstract: A bifilar helical antenna includes an output/input unit formed by disposing a hybrid on a substrate, wherein the surface of the substrate is coated with a metallic conductive layer; the hybrid is a microstrip-line pattern formed by the conductive layer, and it further comprises a ring part and a plurality of transmission ports; and an antenna unit including a shell and an impedance transformer, wherein the shell is a cylindrical hollow tube disposed on the substrate of the output/input unit, on which a first helical line and a parallel second helical line are wound and both the bottom ends of the helical lines are electrically connected together through a resistor; the impedance transformer is composed of a first transmission line and a parallel second transmission line, where both the top ends of the first and the second transmission line are electrically connected to the top end of the first and the second helical line, and both the bottom ends of the first and the second transmission line are electrically
