This letter presents a new type of circularly polarised micro-strip antenna. It is composed of half-wavelength strip conductors and slots arranged along both sides of a microstrip line. Circular polarisation can easily be obtained with this antenna whether the current distribution on the line is a travelling wave or a standing wave. The experimental verification is also presented.
