BAND-STOP FILTER BASED ON MAGNETODIELECTRIC
RESONATOR FROM NATURAL MAGNETIC MATERIAL FOR X-BAND
Band-stop filter based on natural mixed maghemite-hematite crystal tuned by external
magnetic field is suggested and investigated. For various dielectric substrate thicknesses,
maximum frequency shift of 300 MHz, Q-factor variation from 200 to 1300 and 6-20 dB
rejection level is measured in 0-6 kOe field. Band-stop width at -3dB level was 8-52 MHz.
