Abstract :
The design of a single-feed small microstrip antenna with circular polarisation (CP) radiation is described. This design is achieved by cutting slits in the square patch and. By adjusting the lengths of the slits, the microstrip antenna can perform CP radiation with a reduced patch size at a fixed operating frequency. This design also provides a wide CP bandwidth and relaxed fabrication tolerances
