Abstract :
Resonant magnetic antenna with adjusting bandwidth and discrete frequency tuning in wide frequency range is considered. The proposed antenna can be narrowband preselector with adjusting bandwidth and discrete frequency tuning for receivers with wideband input circuit. Structure of antenna with digital control from receiver is considered. The antenna consists of diode switch, wideband antenna amplifier and control circuit. Control signals and supply voltage are from the receiver by means of coaxial cable.
