Abstract
In this work, we present a simple theoretical analysis of a compact rectangular microstrip resonator with stubs. The analytical model is based on a recursive algorithm for a transmission line loaded with capacitive stubs. We calculate the input impedance and the resonant frequency of this resonator and analyse the dependence of these parameters on the number and dimensions of the stubs. The numerical results are compared with those obtained by other methods and with experimental data. Β© 2004 Wiley Periodicals, Inc.

## Abstract In this paper, an efficient neural network model is suggested to determine the input resonant resistance of coaxial fed rectangular microstrip antennas (MSAs) with thin and thick substrates. The NN results are in good agreement with experimental results reported in literature. This meth
The Bruker TEIW double rectangular cavity is commonly utilized for quantitative electron paramagnetic resonance (EPR) spectrometric measurements. The sample, together with an appropriate standard, can be studied simultaneously within such a cavity under identical states of machine tuning and paramet
