Abstract

We have proposed a transverse electromagnetic (TEM) horn antenna for radiated immunity tests in close proximity as specified in IEC 61000-4-39 and evaluated the main characteristics of the antenna required in the immunity tests. The TEM horn antenna has broadband radiation characteristics with a low VSWR and generates a homogeneous field over the entire test frequency range from 380 MHz to 6 GHz.
