EMC Studio v5.0
Glass Antenna Simulation Toolchain with Special Numerical Methods
Complex glass antenna structures could not be simulated satisfactory with standard numerical methods in the past. EMCoS has developed the first accurate and fast approach based on hybridization of MoM solution for 3D objects and a Green function approach for metallic stripes, printed on a dielectric substrate. With this revolutionary method glass antennas can now be easily designed and optimized to reach best reception performance. With support of the numerous EMC features of EMC Studio, emission problems can now be detected more reliable. A full toolchain is provided in EMC Studio for effective modeling and simulation of complex car glass antennas. The toolchain includes:
- Advanced functions for glass antenna importing from native CAD formats and pre processing of initial data in order to obtain accurate computational model
- Special computational method for glass antenna analysis (based on hybridization of MoM solution for 3D metallic and dielectric objects and a Green function approach for metallic stripes, printed on a curved multi-layered dielectric substrate)
- Multiple methods for the treatment of antenna amplifiers and matching circuits
New System Simulation Solutions
Electronic systems are often quite complex. For simulation of different parts of a system different numerical approaches are often necessary. The calculated sub-model behavior can be described by the coupling between the input and output ports. The system behavior information can be stored as a scattering parameters matrix. To get answers regarding the full system, the coupling matrices must be assembled and converted to a model that can be simulated.
EMC Studio 5.0 provides new system simulation solutions for modeling of complex systems based on measured or simulated scattering matrices.
- The coupling behavior can be converted based on Vector Fitting Technique to a equivalent circuit model for full system simulation in frequency or time domain with non-linear components
- New type of device – Touchstone Device – is implemented. It allows to introduce measured or calculated S parameters to system simulation model
Near Field Source Solution
For simulations of complex systems it is often difficult to model and simulate simultaneously different types of objects. For example, modeling of metallic part of car body can be efficiently done using Method of Moments; however simulations of complex devices may require circuit analysis and/or separate analysis of radiation from PCB or its housing.
EMC Studio 5.0 supports new type of external excitations for investigation of sub system radiation – Near Field Source. This equivalent source provides possibility to include simulated or measured radiation data from components into a corresponding simulation model in EMC Studio.
Low Frequency Smart/ Keyless Entry Antenna Simulation
Smart/ Keyless Entry Systems become more and more popular. System consists of several antennas transmitting signals. Several antennas are distributed in the car and one antenna is located in the driver ‘remote key’. Parts of antennas are oriented to out-vehicle zone, and another part is oriented to the in-vehicle zone. Location detection antennas are normally realized as coil antenna wounded around a ferrite core.
Modeling and simulation of low frequency coil antennas with ferrite core can now be effectively done in EMC Studio 5.0.
For convenient analysis of zones with high and low radiated field levels EMC Studio 5.0 provides also new special post-processing options.
Models and Devices Library
Models Library available in EMC Studio 5.0 allows to prepare parametrically defined basic components of a system to be simulated for further import to the complete simulation model. Included objects can be easily customized based on previously defined parameters.
Currently the following simulation ready models are provided in Models Library:
- Antennas (Coil, Conical, Glass, Horn, Patch, Wire, Reflector)
- Microstrip Structures
- TEM Devices
- Filters
New Ideology of EMC Studio Objects and Models
EMC Studio 5.0 provides new ideology of EMC objects and models. With new ideology EMC Studio project may be divided into several independent components (groups) called “objects” that may contain different parts of the whole simulation model.
Multi-objects ideology provides possibility to export the whole project or its part to external *.emm (EM Model) files and then import these files into other simulation projects.
Microstrip Patch Antenna Solution
Microstrip patch antennas are commonly used antenna types today; particularly in the frequency range of 1 to 6 GHz.
EMC Studio 5.0 provides an advanced toolset and computational techniques that enable construction and effective analysis of microstrip antennas. Special Green function approach can be successfully applied for simulation of metallic structures printed on dielectric substrates.
New CAD Formats Support – STEP and Parasolid
EMC Studio 5.0 supports geometry import from STEP (*.stp, *.step) and Parasolid (*.x_t, *.x_b) file formats.
