A novel miniaturized microstrip Wilkinson power divider with capacitor loading is presented in this article. The new divider not only effectively reduces the occupied area to 45% of the conventional one at 1.0 GHz, but also has good harmonic suppression performance. Furthermore, the new structure has only two variable parameters and can be easily designed. The design is validated both by simulation and measurement. © 2011 Wiley Periodicals, Inc.

A novel method for sensor fault diagnosis based on support vector machine (SVM) prediction model was proposed. This paper put forward the principle of SVM condtruction process and the system parameters obtained from using dynamic model identification of sensor. The sensor fault was diagnosed on line by prediction model, which avoided that BP algorithm must have mass data and is likely to fall into local minimum point. Compared to the traditional motheds, it was much more effective and accurate.
