Abstract

In this paper a new ultra wide band exponential transverse electro-magnetic (TEM) horn antenna with binomial impedance taper is presented. The binomial distribution is used for the impedance taper along the length of the proposed antenna. Using binomial distribution for the impedance taper causes the antenna to have minimum VSWR and flat gain in a wide frequency band. The proposed antenna was manufactured and its performance was compared with the antennas of the same size with exponential, Klopfenstein and triangular impedance tapers. Measurements show that the antenna has VSWR less than 2 in the frequency band from 3 to 15 GHz and less than 2.5 from 2 to 16.3 GHz. Having very good directional pattern and flat gain in a wide frequency band are significant characteristics of this new proposed antenna.
