Designs of reducing the overall antenna size for a circularly polarized slot antenna are studied. The miniaturized design is based on a square-ring slot antenna fed with an L-shaped coupling strip, and it is performed by varying the slot shape and simultaneously cutting the ground plane. Two compact prototypes are implemented and measured. For the first one prototype, both the ring slot and ground plane have a narrow rectangular shape, and experimental results demonstrate that it can provide monopole-like radiation as well as broadband circular polarization operation. As for the second one, its overall antenna dimensions are further reduced to be less than 0.1 λ02, and it has a 3-dB-axial-ratio bandwidth of about 4%. For the two prototypes, processes of the miniaturized designs are shown, and details of the experimental results are given along with the simulated results carried out by HFSS.
