For the classical circuit designs and the corresponding layouts we are using the most recent version of Altium Designer. The used libraries are generated and maintained by us,
so we know the content details and references, allowing to keep the libraries content traceable.
The unobtrusive, daily tools are often extremely precious, because they allow the continuous traceabililty of the established designs.
Circuit design, Schematic. For complex systems the schematics of the complete design inside
Altium Designer organized in hierarchical order. This eases the handling
and the readability of the overall design.
Circuit Design, Layout. In case the used elements have 3D bodies, is it possible to visualize
the developed layout as a 3D model. This allows to virtually mount the major elements and to verify the final mounted
situation at an early stage.
For many years we have been active in the design, construction and optimization of different antenna structures. The already
built antenna types are heterogenicly spread among the possible families. Some typical examples are:
LogPer antenna 100MHz to 2.5GHz
Crossed-LogPer antenna made in inox
Railway antenna 790MHz to 6GHz, in frequency bands, including type approval DIN EN50155
Linear polarized patch antenna
Circular polarized patch antenna, some of them multiband
Helix antenna 2GHz
PIFA PCB antenna in different styles
Horn antenna, narrow band and broadband designs
Electrical small antennas (Small Antennas) integrated into products
Dualband PCB-antenna. The antenna is used in a mobile unit and operates in two ISM bands
below 1GHz. Displayed here is the simulated far field at 400MHz, where we see the peaks and nulls of the radiation pattern.
The feeding point is at the number combination 11.
Dualband PCB-Antenna. The antenna is used in a mobile unit and operates in two ISM bands
below 1GHz. Displayed here is the simulated far field at 900MHz. Due to the large size of the structure in relation to the
wave length the structure forms a pattern with multiple peaks and constrictions.
High frequency circuit design using simulation tools
Simulation tool MWO. Due to the unified database the layout is generated in parallel,
while drawing the schematic. Therefore is the additionally required work to finalize the layout is very small, only by adding
some small supplements.
Simulation tool AXIEM. In the 3D view the mesh or the surface currents can be displayed. By
using the circuit extraction function electromagnetic (EM)-structures can very easily be derived from the existing layout.
Simulation tool VSS. Typically transmission systems, receivers, radar systems or antenna
arrays are simulated with VSS. Specific for receivers are bit error rates or the constellation diagram of the modulated
