【Abstract】 A new structure of dielectric waveguide coupler is described, which has advantages such as very Hat frequency response over 50 percent bandwidth. Theoretical analysis by a superposition of normal modes is presented. Finally, experimental results at 3mm waveband show good agreement with theoretical calculations.更多还原
