Modified TEM Horn Antenna for Broadband Applications

In this paper, the authors present a novel method to enhance the pattern characteristics of the TEM horn antenna for 2-14GHz frequency band. The conventional TEM horn antenna introduces some fluctuations in the main lobe radiation pattern over the higher frequencies, i.e., 10-14GHz. This motivated them to propose a new method to remove the aforementioned impact by carving an arc shape to the open end of exponentially tapered plates. The associated curvature of this arc is optimized to completely remove the fluctuation.
