The TEM horn with elliptic E‐plane profile has been shown to give extremely wide bandwidth performance as far as VSWR and gain is concerned. In this article, the variation in radiation pattern versus frequency is explored, and it is shown that, dependant on choice, E‐plane or H‐plane radiation patterns that are virtually independent of frequency can be obtained.
