The results show that in the case of the radiation of the pure te11 mode, dh is less than d with their difference ranging from 0. 1db ~ 0. 8db, and de is larger than d with a difference between - 1. 9db and - 1db, and that in the case of the radiation of the mixed modes of te11 and tm01 with power proportions from 5 % to 30 %, dh is still close to d with the maximum difference less than 1db, while the difference between de and d can be as large as - 4db
Te11模中含有一定量的tm01模式時,比如, tm01模式占功率比為5 - 30 % , dh仍接近模擬值d ,最大誤差小於1db ;而d與de的最大差值將近- 4db 。可見, h面的方向性系數與實際的方向性系數偏差要小一些。
