A single-fed compact circularly-polarised (CP) microstrip antenna is designed and experimentally demonstrated. By embedding the symmetric-slit in the radiation patch and protruding a pair of perturbation elements at the boundary of the centre square slot, the proposed antenna can obtain good CP performance with effective size reduction at a fixed frequency operation. Meanwhile, an impedance transformer is utilised for impedance matching.
