Abstract:
1. A broadband ferrite-loaded loop antenna, comprising: a low loss ferrite core having a width-to-height ratio of approximately 24 and a depth-to-height ratio of approximately 6; an antenna feed plate assembly centered about a long axis of the ferrite core, having a width-to-height ratio of approximately 6 and a width-to-depth ratio of approximately 1; a balanced feed located at a center of the antenna feed plate assembly, positioned on a radiating side of the antenna; a low loss center element in the ferrite core, the center element having at least one of a loss tangent and a permeability that is lower than the ferrite core; and a grounding surface coupled to the antenna feed plate assembly, wherein the broadband ferrite-loaded loop antenna operates within a range of approximately 2-30 MHz and has a comparable receiving versus transmitting performance characteristic.
