Abstract :
An expression for the input impedance of a short-circuited, linearly-tapered transmission line is derived. The use of tapered slots in a corrugated horn is proposed as a means of broadening their bandwidth to greater than 3:1. Test results are presented for an experimental horn operating over the full 7.5¿18 GHz range of DR14 waveguide.
