Radiation from discontinuities in strip-line

A method of calculation, which should be adequate for strip-lines of small spacing, is proposed for the evaluation of the radiation of line-above-ground configurations. It is shown that an open-circuit is appreciably worse, from the point of view of radiation loss, than short-circuit with a right-angle corner at an intermediate level. The radiation from a matched post is slightly worse than from the short-circuit, but it should be capable of considerable improvement by the use of a terminating frame antenna. Formulae are also given for the effects of reactive posts, with applications to a simple resonator.
