Zr. Xu et al., A STUDY OF RADIATION FROM CIRCULAR GROOVE GUIDE HORN, International journal of infrared and millimeter waves, 16(11), 1995, pp. 2003-2009
A novel horn antenna for millimeter waves based on circular groove gui
de is presented and investigated in this paper. Its radiation patterns
are calculated by employing the aperture field method. The patterns o
btained by experiment show agreement with calculated results.
