Technique of applying a small DC magnetic field to a ferrite antenna substrate to reduce the magnetic loss and therefore improve the radiation efficiency.
About
Technique of applying a small DC magnetic field to a ferrite antenna substrate to reduce the magnetic loss and therefore improve the radiation efficiency. Experiments show increased resonance frequency, radiation efficiency and gain of the miniature ferrite antenna.
Key Benefits
The permeability of ferrite increases the miniaturization factor and bandwidth of the anteena. The magnetic field reduces the magnetic loss tangent of the ferrite substrate. High antenna gain
