A thin planar absorbing structure of Jerusalem cross slot (JCS) is designed, which has the virtue of wider bandwidth and broader adjustment range. The absorption frequency band can be flexibility adjusted by slot parameters. The influences of various structure parameters of JCS, incident wave polarization and variation of incident angles on the absorption characteristics are analyzed to provide guidance on the theoritical design for practical application. The validation and effectiveness of the proposed design was simulated using high frequency structure simulator (HFSS). The simulation result shows that zero point of reflection phase is at 9.7 GHz and the relative bandwidth is about 15.5%. The improved design is characterized by its wider bandwidth and adjustable by slot parameters. The influences of various structure parameters of JCS, including incident wave polarization and variation of incident angles on the absorption properties, are analyzed to provide guidance on the theoretical design for practical application. The loaded resistance can be adjusted to obtain the optimum absorbing performance.
