Abstract :
It is demonstrated that the admittance of thick tubular antennas can be accurately computed by using a ray-optical technique for finding the reflection from the end. The theory gives good results for a radius as small as 0.2 of a wavelength. The results are compared with a numerical solution by Chang [1].
