Frequency-domain analysis of microstrip filter and antenna using adaptive frequency sampling moment method

摘要

In this paper, an adaptive frequency sampling technique is applied to the moment method for the analysis of microstrip filter and patch antenna. The analysis of microstrip low-pass filter and patch antenna in the frequency domain has been usually done with uniform frequency step. An adaptive frequency sampling technique can significantly reduce the time taken for the analysis through the frequency range without reducing the accuracy of the results.
