    Abstract: A compact size ultra-wideband (UWB) microstrip antenna with improved performance is proposed in this communication. In this article, the design of the antenna, which is based on the interaction between the circular patch and the rectangular slot cutting in the metal ground plane, as a result the required starting frequency can be achieved due the c...

    Abstract: In this paper, further results on the problem of the model structure validation for closed loop system identification are proposed. One probabilistic model uncertainty is derived from some statistical properties of the parameter estimation. The uncertainties bound of the model parameter is constructed in the probability sense by using the inner pro... Show More
