    • There is disclosed an active impedance matching network for an electrically-small antenna. The network comprises a plurality of electrically-parallel branches connected between a transceiver and the antenna. At least one branch comprises a pre-matching transformer, a negative impedance converter and a post-matching network connected in series with each other. There is also disclosed a matching network for connecting an electrically small antenna to an RF source or load. The matching network comprises a negative impedance converter, a pre-matching network for connecting the negative impedance converter to the antenna and a post-matching network for connecting the negative impedance converter to the RF source or load. The post-matching network comprises a plurality of parallel branches between the negative impedance converter and the RF source or load. Each branch includes a separate post-matching impedance transforming circuit, and each branch is configured to carry a different frequency band.
    • 公开了一种用于电小天线的有源阻抗匹配网络。 网络包括连接在收发器和天线之间的多个电并联分支。 至少一个分支包括彼此串联连接的预匹配变压器,负阻抗变换器和后匹配网络。 还公开了一种用于将电小天线连接到RF源或负载的匹配网络。 匹配网络包括负阻抗转换器,用于将负阻抗转换器连接到天线的预匹配网络和用于将负阻抗转换器连接到RF源或负载的后匹配网络。 后匹配网络包括在负阻抗转换器和RF源或负载之间的多个并行分支。 每个分支包括单独的后匹配阻抗变换电路,并且每个分支被配置为承载不同的频带。
