MULTIBAND, SINGLE FEED ANTENNA

WIPO Patent Application WO2002039540

A9

A multiband antenna operates in at least a first frequency band and a second frequency band, a higher frequency band. A dipole has a first conductive leg (6) and a second conductive leg (8) and may be directly fed between the first and second legs. At least a portion of the first leg of the dipole has a meander configuration (10). The first leg (6) has an electrical length of about one-quarter wavelength, or an odd multiple thereof, in the first frequency band and the second leg (8) has an electrical length of about one-quarter wavelength, or an odd multiple thereof, or more in the first frequency band. A non-driven parasitically-excited conductive element (18) is closely spaced to the first dipole leg and is electrically connected to the second dipole leg (8). The parasitic element (18) has an electrical length of about one-quarter wavelength, or an odd multiple thereof, in the second frequency band.
