Smithdom multiband antenna

摘要: An improved broadband off-center fed dipole antenna, the Smithdom capable of resonating at multiple frequencies with a near integer relationship between fundamental and harmonic standing wave ratio less than or equal to 2:1 desired without need an antenna tuning device. The comprises first radiating section having inner line electrically coupled balun transformer trap outer connected insulator. A second is has another insulator secured its other end.
