The TEM horn aiiteiiiia, in its niost basic form, consists of two metallic ?#lHQT  
sheets, each ail isoscclcs trianglc will1 tlic angle at the apex being a. The lQqP4-E?  
planes of‘ these triangles are separaled by the angle p, aud the antenna is &l~9FE*  
fed by a two-wire transmission line connected at the apices. Fig. 1 shows :NynNu'  
the image equivalent of this structure: a single triangular sheet fed throqgh 7qLB9r  
a metallic image plane by a coaxial line. The structure described above Behaves &W{<Yf9  
as a transmission line and will support a TEM wave. The characteristic
