Smithdom improved multiband antenna and method

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