Open the CIPO recordAbstract From the Canadian patent
A transistorized microwave oscillator comprises an oscillator circuit including a transistor and a feedback capacitor. The oscillator circuit generates a fundamental oscillating frequency and harmonic components. A cutoff waveguide is connected to the oscillator circuit for cutting off the fundamental oscillating frequency and unwanted lower-order harmonics to provide a higher-order harmonic. According to the invention the feedback capacitor is utilized as the coupling circuit for extracting the desired harmonic from the oscillator circuit. Also, the feedback capacitor is concurrently used as an antenna. The nth harmonic of the fundamental frequency radiated from the antenna is extracted …
