ABSTRACT:
A wideband VHF antenna operable simultaneously on multiple frequencies hag an instantaneous bandwidth greater than one octave and having a total length less than one-quarter wavelength at the lowest operating frequency. A wideband impedance transformer is connected to the antenna total radiating structure at the feed point. The radiating structure comprises a conductor secured to a dielectric whip. The conductor is comprised of two sections of length L1 connected by a short length of electrical connector to form a large loop. The radiating structure further comprises a second electrical conductor of length L2 connected by another short length of electrical connector so as to form a small loop. The length L2 conductor is disposed in the neutral plane between the two conductor sections of length L1.
