| Abstract: | 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. |
