Abstract

In this paper a nonradiative symmetrical dielectric grating waveguide and its application to MMW DBR Gunn oscillator is presented. The width of symmetrical dielectric strips is selected carefully in order to avoid the leakage and resonance effect. A DBR oscillator has been designed and tested, Its power output is 70-100mW, and frenuency stability is better than 10-6 at 40 GHz which is 10 times better than that of MMW DBR oscillator using the inverted strip dielectric waveguide(1).
