摘　　要：为解决传统合路器体积重量与损耗不能兼顾的问题,提出了一种用于智能天线的内置一体化合路校准网络,采用微带结构,由带阻合路器和校准网络组成。实测结果表明,合路校准网络的通带插损小于0.7dB、通带回波损耗小于-15dB、阻带抑制大于30dB。该一体化合路校准网络具有集成度高、体积小、重量轻、工艺简单等特点,有利于减小智能天线的体积及重量。In order to solve the problem that traditional combiners can＇t take volume, weight and loss into account simultaneously, an internal integration of combiner and calibrating network used for smart antennas is proposed. It adopts microstrip structure and consists of a bandstop combiner and a calibrating network. Measurement results show that its passband insertion loss is less than 0.7dB, while passband return loss is less than -15dB and stopband restrain is more than 30dB. The integration of combiner and calibrating network proposed has the advantages of high integration, small volume, light weight and simple crafts, which is good for reducing the antenna＇s volume and weight.
