ABSTRACT:
An antenna is provided which exhibits an overall shortened length with respect to the length of the conventional sleeve dipole type antenna. The antenna includes an upper radiating element coupled to a tank circuit to induce resonance at a first resonant frequency and further includes a helical element electrically coupled to a sleeve member which cooperate to resonate at a second resonant frequency.
