频率选择表面天线复用副面的研究

Antenna Multiplexer of Frequency Selective Surface

在毫米波和红外相结合的复合系统研究中,结合飞行器雷达天线系统的设计需要,在理论分析的基础上,采用频率选择表面(FSS)来设计天线复用副面。实验结果表明,该副面实现了透过毫米波和反射红外光的双工性能,并适于双色和多色红外复合系统。FSS天线复用副面的材料应尽量选用厚度适中、平整光洁的低耗衬底介质敷铜基板,以达到更为理想的设计效果。

In combining the millimeter wave with the infrared wave system, this paper uses the frequency selective surface （FSS） to design the antenna multiplex based on the theoretical analysis. Experimental results verify that the multiplex technology can realize the duality characteristic of passing through the millimeter wave and the refecting infrared wave. The multiplex is suitable for the double-color and multi-color combined infrared system. FFS antenna multiplexer must use the bright copper clad laminates with the low power and the moderate thickness.
