Abstract

According to Floquet's Theorem and Brillouin Principle , a two beam radiation antenna of inverted strip dielectric waveg- uide (ISDG) with grating structures for both dielectric grating and metallic strip grating is investigated and tested, The radia- tion characteristics of a 61 GHz dual beam flat antenna with symmetry in respect to the broadside direction are plotted. Its beam width in E plane is 4. 5Ã‚Â°, Millimeter Wave dual beam flat antennus will be of potentially wide applications , such as air- craft , tracking radar , Collision avoidance or speed measure- ment with a required high accuracy and rejection interference. A 61 GHz integrated Doppler System with high sensitivity has been constructed as well.
