The frequency domain solver may also be the method of choice for narrow band problems such as filters or when the usage of tetrahedral grids is advantageous. In these cases it is advantageous to solve the problem by using the frequency domain solver. The transient solver is less efficient for electrically small structures that are much smaller than the shortest wavelength. This solver is remarkably efficient for most kinds of high frequency applications such as connectors, transmission line, filters, antenna and more. The most fixable tool is the transient solver, which can obtain the entire broadband frequency behavior of the simulated device from only one calculation run (in contrast to the frequency step approach of many other simulators). Furthermore, the frequency domain solver supports both hexahedral and tetrahedral mesh types. The frequency domain solver also contains specialized method for analyzing highly resonant structure such as filters.

Since no method works equally well in all application domains, the software contains four different simulation techniques (transient solver, frequency domain solver, integral equation solver and eigenmode solver) to best fit their particular applications.

Finally the paper is concluded in Section 4.ĬST MWS, the microwave simulator, which is based on Method of Demand (MoD) approach which allows using the simulator or mesh type that is best suited to a particular problem, applying these highly advanced techniques normally increases the accuracy of simulation substantially in comparison to conventional simulators.
In Section 3 we present the MWCNT ink parameters, antenna design, and simulations used in this comparative study. This paper is organized as follows, in Section 2, we present a condense overview about both CST MWS and ADS. These advantages are lower mass density and high resistivity against corrosion, the two simulators CST MWS and ADS are used to evaluate the return loss, matching impedance, resonant frequency, bandwidth and far field radiation patterns.

Using MWCNT ink instead of copper for microstrip patch antenna gives main benefits against copper. The results are given for both MWCNT and Copper characterizations.
We show a close agreement in the results obtained by the two simulation software's CST MWS and ADS. The antenna gain is found to be –12.5 dBi at 1.22 GHz for MWCNT and is found –12.05 dBi at 1.25 GHz at CST MWS and the antenna gain is found to be –11.85 dBi at 1.235 GHz for MWCNT and is found –12.25 dBi at 1.243 GHz at ADS and the antenna gain is found to be –4.25 dBi at 2.47 GHz for MWCNT and is found –4.01 dBi at 2.53 GHz at CST MWS and the antenna gain is found to be –4.23 dBi at 2.47 GHz for MWCNT and is found –4.88 dBi at 2.45 GHz at ADS. We show the meandering of the surface current on the radiating in spiral patch. The reflection coefficient is –12 dB at 1.2276 GHz for MWCNT and –13 dB at 1.25 GHz for the copper simulated by CST MWS and reflection coefficient is –12.235 dB at 1.234 GHz for MWCNT and –18.36 dB at 1.243 GHz for the copper simulated by ADS and the reflection coefficient is –27dB at 2.47 GHz for MWCNT and –13 dB at 2.53 GHz for the copper simulated by CST MWS and the reflection coefficient is –26.08 dB at 2.48 GHz for MWCNT and –17.031 dB at 2.47 GHz for the copper simulated by ADS. In this paper, we compare a dual-band, square spiral microstrip patch antenna constructed from Multi-Walled Carbon Nanotubes (MWCNT) ink for wearable application simulated by Computer Simulation Technology Microwave Studio (CST MWS) by our work simulated by Advanced Design System (ADS) electromagnetic simulator using the same material characterization.
