Focusing properties―especially the focus width―of circular airy beams (CABs) with emission angles are investigated for microwave near-field applications. The CABs are described as the solutions of the para-axial wave equation which are numerically solved. The suggested CAB can produce a narrow focal point with a 3-dB-width of 0.23λ and requires a relatively small phase shift in the aperture. The results are verified by a theoretical model for antenna arrays composed of half-wavelength unit cells.
