Ferrite manufacturers for Microwave ferrite devices
Ferrite manufacturers for Microwave ferrite devices
(OP)
Can someone recommend a commercial manufacturer of Ferrite rods and rectangles for use in microwave devices at frequencies in the 2-500 Mhz range.
I'm trying to make a low frequency ferrite loaded antenna, hence references on low frequency ferrite loaded antennas in the 2-100 mhz range would be appreciate too.
could someone also give me some tutoring on using ferrites
thanks,
kch

RE: Ferrite manufacturers for Microwave ferrite devices
Basically you take a ferrite rod, wrap some wire around it making a big inductor. You then resonate it with a series variable capacitor. You wrap a smaller coil around the rod to couple energy out of the resonator.
The antenna will pick up signals at the frequency where the L-C circuit is tuned to resonate. It is fairly directional, like a dipole antenna. Also, it is fairly narrow band.
