在电子不停车收费（ETC）系统中，研究了一种基于三元乙丙橡胶片与磁粉复合的薄吸波材料在5.8GHz频段的吸波性能。结果，由于设计值和制造值的厚度之间的差异，匹配频率偏移到5.94 GHz;然而，确认对于用作ETC系统中的通信手段的圆偏振波，在5°至45°的入射角范围内可以获得25 dB或更大的吸收。因此，通过控制吸波体的厚度，可以实现满足ETC商业化要求的薄橡胶吸波体。© 2006 Wiley Periodicals，Inc.

A thin wave absorber based on ethylene‐propylene‐diene methylene rubber sheet combined with flaky magnetic powder is examined at 5.8 GHz in electronic toll collection (ETC) system. As a result, the matching frequency is shifted to 5.94 GHz because of the difference between the thickness of a designed value and a fabricated value; however, it is confirmed that the absorption of 25 dB or more can be obtained at the incident angle ranging from 5° to 45° for circularly polarized waves used as means of communications in ETC systems. Therefore, the thin wave absorber based on rubber sheet satisfying commercial requirements of ETC can be realized when the thickness of the absorber is controlled. © 2006 Wiley Periodicals, Inc.
