Abstract :
Dual-band magnetic-based 3D antennas were introduced and shown to achieve efficient radiating elements that operate over a low frequency band. The resonant frequencies of the antenna system can be designed for a broad range of frequencies by tuning separately the near field resonant parasitic elements. We are continuing our investigations to determine if other structural variations can further reduce the return losses at the lower VHF frequencies or could better control the separation between the two resonance frequencies.
