Previously, a TEM horn with ultra wideband performance had been described. The horn made use of an elliptic plate separation profile, while the plate width was determined by an optimal impedance function and the characteristic impedance equations for microstrip. In this article, it is shown that if the impedance equations for parallel plate waveguide are employed in the calculation of the plate width, extreme bandwith of more than 70:1 for a VSWR of 2:1 can be achieved. © 2008 Wiley Periodicals, Inc.
