Abstract-In this paper, a new method to analyze arbitrary shaped microstrip patch antennas is introduced. This method uses the multiport network model (MNM) together with a mathematical approximation called the "Padé approximation" such that the antenna input impedance obtained from the multiport analysis is approximated as a rational function of polynomials. Then, the roots of the denominator of this rational function are used to determine the antenna resonant characteristics. This new method is more time efficient than the standard multiport analysis because the evaluations are made at a single frequency. In the standard method, evaluations are made at multiple frequency values throughout the analysis. Results obtained by the new method are verified using the examples of rectangular and slot loaded compact microstrip patch antennas. Computational efforts for both procedures are presented.

This paper presents a switched capacitor circuit simulator, AWEswit. AWEswit exploits the cyclical reconfiguration of switched capacitor circuits through a sequence of continuous-time circuits. It employs Asymptotic Waveform Evaluation (AWE) to estimate the response of the state variables (capacitor voltages) in each switching phase. For accuracy, a horizontal Pad6 sequence is employed to extract dominant pole models for the response of the state variables. In addition a general technique to handle complications in the AWE analysis resulting from loops of voltage sources and capacitors is presented. This technique makes AWEswit compatible with that class of switched capacitor simulators which operate in the charge-voltage regime.
