1. Introduction M0yv=g  
Th e transverse electromagnetic (TEM) horn antenna is a popu- lar broadband antenna. The basic antenna is a simple design,
-^+fZBU;  
consisting only of two triangular metal plates and a feeding structure. &+
"<ia(  
Neglecting the feeding structure for the moment, the horn is 9HB+4q[  
described completely by only three variables: a , p, and s. As >v2/0>U  
shown in Figure 1, a is the angular width of each plate, p is the t'1g+g  
angular separation between the two plates, and s is the length, o%7-<\qS  
measured from the drive point to a comer of the plate. _iu~vU)r  
Much of the previous research has focused on modifying the 'Fy"|M;2  
antenna’s structure to improve the performance. These modifications ,oykOda:|  
include resistive loading along the plates [ I , 21 and shaping ulE5lG0c  
of the plates [3]. What is interesting is that there is very little 1*" 7q9x  
design information available for the hasic TEM horn, as compared oR7[[H.4
