摘要

本文详细分析了一种用于天线调谐的SOI CMOS可调谐电容器。给出了开关电容网络的设计表达式，并将整个网络的质量因子表示为设计参数的函数。通过将130 nm SOI CMOS可调谐电容与印刷缺口天线相结合，描述了其在天线孔径调谐中的应用。所提出的可调谐多波段天线可在420 MHz至790 MHz范围内调谐，相关辐射效率在33-73%范围内。

SOI CMOS tunable capacitors for RF antenna aperture tuning

This paper provides a detailed analysis of a SOI CMOS tunable capacitor for antenna tuning. Design expressions for a switched capacitor network are given and quality factor of the whole network is expressed as a function of design parameters. Application to antenna aperture tuning is described by combining a 130 nm SOI CMOS tunable capacitor with a printed notch antenna. The proposed tunable multiband antenna can be tuned from 420 MHz to 790 MHz, with an associated radiation efficiency in the 33-73% range.
