Experimental Study of the Characteristics of Ultrawideband TEM Horn with the Dielectric Filling

The article describes a fabricated TEM horn with an inhomogeneous dielectric filling. Experimental measurements were provided and important results were achieved. The gain in main direction of an ultrawideband TEM horn with an inhomogeneous dielectric filling of the space between its lobes was obtained using the substitution method. Also, the values of the VSWR of the studied antenna were found. A comparison of the experimental results with those obtained earlier in modeling shows their high similarity.
