GENERATOR FOR MICROWAVE TREATMENT Russian patent published in 1999 - IPC

FIELD: medical devices, in particular, microwave equipment for affecting biologically active regions by electromagnetic fields of high and very-high frequency. SUBSTANCE: emitting antenna is designed as coaxial waveguide piece, which outer part is short-circuited on one side. Inner conductor is designed as round waveguide piece, which length is equal to length of outer part and extends outside by distance, which is equal to quarter wave in waveguide. It contains source of electromagnetic oscillations, which is designed as noise generator, gas-discharge tube which is located in glass bulb with coaxial electrodes. EFFECT: matching of emitter to region under treatment, sharp direction pattern, increased bandwidth of output frequencies. 2 dwg
