Ferrite receiving antennas
WebJul 25, 2024 · A circular sector-shaped dipole antenna with meandered arms based on an artificial magnetic conductor (AMC) is proposed in this study. A compact unit cell of the AMC operating within 19–485 MHz is designed using a ferrite material, which exhibits high-permeability characteristics in the high-frequency (HF), very-high-frequency (VHF), and … WebJul 31, 2024 · A wound horizontal ferrite rod antenna receiving a 100KHz signal as for RF direction finding. If a second ferrite rod, bare with no windings is placed/attached/joined parallel next to the receiving wound one; would the signal coming from the direction of the bare rod be sensed as weaker ? W= wound receiving rod. B= bare rod.
