ABSTRACT:
A broadband off-center fed dipole antenna capable of resonating at multiple frequencies with a near integer relationship between fundamental and harmonic frequencies and with standing wave ratio of less than or equal to 1.5:1 at desired frequencies without the need of an antenna tuning device. One preferred embodiment of the antenna comprises a first radiating section having an inner line electrically coupled to a balun transformer and a trap and an outer line electrically connected to the trap and an insulator. A second radiating section is connected to the balun transformer and has another insulator secured to its other end.
