Abstract :
This letter proposes a broadband antenna system with omnidirectional features, operating from 2 to 440 MHz. The basic antenna structure is the bifolded monopole, recently proposed as multimode high-frequency (HF) naval antenna, which is here augmented with a top-mounted discone mainly operating in the very-high-frequency (VHF) band. A mechanical and electrical integration strategy, which can be also extended to other antenna typologies, based on the lumped impedance loading to reduce the interantenna coupling, is described
