Abstract :
A singly-fed circular patch antenna generates a circularly polarised conical beam with the help of two perturbation elements. The location of the feed point relative to the perturbation elements determines the rotational sense of the circularly polarised wave. Theoretical and experimental results for the radiation pattern and return loss are presented.
