Abstract

The authors present a set of experimental results which demonstrate that it is possible to control the level of harmonic and spurious radiation emitted from a microstrip patch oscillator by means of at least two mechanisms. A discussion of these mechanisms is included, and it is also argued that an unambiguous method of classifying similar results is required.
