Novel microwave high‐Q point‐defect‐cavity (PDC) resonators based on metallic photonic crystals (M‐PhCs) are experimentally studied. After the illustration of the band structure of M‐PhCs, the first two resonant modes of a PDC are computed by supper‐cell methods. The results show that the Q‐value of M‐PhC PDCs is almost the same as that of the traditional waveguide cavity resonators. Moreover, the PDC is then fabricated and experimentally measured. The measured resonant frequencies and Q‐factors are compared with the calculated ones to validate our computation and show the property of the proposed PDC.
