| Outline of Final Research Achievements |
In this thesis, low cost and high performance Push-Push oscillator arrays with simple circuit structure are studied. The following 3 types oscillator arrays are investigated, an oscillator array consists of reflection type Push-Push oscillators and a mutual coupling type coupling circuit, which is connected between the sub-oscillators in the Push-Push oscillators, an oscillator array consists of reflection type Push-Push oscillators and a injection locking type coupling circuit, which is connected between the resonator in the Push-Push oscillators, an oscillator array consists of positive feedback type Push-Push oscillators and a injection locking type coupling circuit, which is connected between the feedback loops in the Push-Push oscillators. It is possible that very wide range beam steering is achieved because the phase shift of the output signals is twice as large as compared with the phase shift of the signal in the coupling circuit due to the Push-Push principle.
