  • Omnidirectional resonant antenna
    Patent number: 7170448
    Abstract: An omnidirectional resonant antenna in a half-plane or in the whole plane comprises a single radiating electric conductor (26) having at least three abutted wires (28, 30, 32), the length of each wire and the orientation of the wires relative to one another determining the global orientation of the electric conductor. The wires are oriented along at least three different spatial directions and the lengths of the wires are designed to obtain an omnidirectional global radiation of the electric conductor in a half-plane or in the whole plane.
