The Characteristics of Impedance and Radiation Patterns of Half Wave Slot Antenna on the Wide Surface of Rectangular Wave Guide

구형 도파관 벽면에 뚫은 반파장 스롯트 안테나의 복사모양과 임피단스

The radiation patterns and impedance of the half wave solt on the wide side of rectangular wave guide are analyzed. The measuring methods and procedures are described. And that the experimental data of the pattern and impedance of the slot are presented which are consistent with the theoretical values. The causes of error are also considered and are believed to be tolerable for the pattern and input impedance measurements. The usefulness of the slot antenna tested are also described.
