Abstract

In an aspect, the disclosed technology relates to embodiments of a lossy ferrite-core and dielectric-shell (LFC-DS) structure in an axial-mode helical antenna (AM-HA) or a meandered dipole antennas. The instant topology can be used to facilitates the broader use of ferrite materials, including lossy ferrite material, for a miniature AM-HA or meandered dipole antennas, e.g., by overcoming the lossy characteristics of the lossy ferrite. The resulting miniature AM-HA can be used for high frequency operation, including at over 1 GHz, making the instant topology suitable for very high frequency (VHF) and ultra-high Frequency (UHF) applications.
