In this paper, we introduce a phase modulated zone plate to generate the circular symmetric Airy beam (CSAB) with abruptly autofocusing characteristic at 30GHz. This phase modulated zone plate is a phase combination form of a radial phase plate and a lens, which would make the conventional generation system of CSAB more compact. Based on full wave simulation, the unique abruptly autofocusing is explored in the field of millimeter wave. Even if the metal plate is placed in front of the phase modulated zone plate, the focusing can still be well obtained, which provides a potential advantage in millimeter-wave sensing.
