1. A multiband antenna operable in at least a first frequency band and a second frequency band higher in frequency than said first frequency band, comprisinga dipole having a first conductive leg and a second conductive leg, adapted to be directly fed between the first and second legs, at least a portion of the first leg of said dipole having a meander configuration, said first leg having an electrical length of about one-quarter wavelength, or an odd multiple thereof, in said first frequency band and said second leg having an electrical length of about one-quarter wavelength, or an odd multiple thereof, or more in said first frequency band, and a non-driven parasitically-excited conductive element closely spaced to said first dipole leg and electrically connected to said second dipole leg, said parasitic element having an electrical length of about one-quarter wavelength, or an odd multiple thereof, in said second frequency band.
