CST market overview

CST offers products suitable for a wide range of electromagnetic design tasks, capable of simulating numerous components and systems.

Together, the products in the CST STUDIO SUITE® family can carry out electro- and magnetostatic, stationary, low-frequency and high-frequency simulations, as well as being able to calculate the effects of EM fields on substances as diverse as magnetic materials, biological tissues and charged particles. Tight integration with third party tools extends the application range even further.

The applications of CST software are almost limitless; among the devices that CST products have been used to simulate are couplers, filters, connectors, antennas, inductors, capacitors, PCBs, waveguides, travelling wave tubes, optical devices, sensors, actuators, electrical machines, SAR, MRI coils and cable harnesses, to name but a few.

Worked examples of applications of CST software are being added all the time. These can be found sorted by application area in the menu on the left, or through the site search at the top of each page.

CST STUDIO SUITE Simulations Replace Prototype Builds For Convergentia

CST STUDIO SUITE Simulations Replace Prototype Builds For Convergentia Document type
Portable devices such as smartphones and tablets nowadays contain many wireless systems, including cellular, Wi-Fi and GPS. Each system requires a functional antenna, since poor antenna performance may lead to a bad user experience in the form of low data throughput or poor coverage, and can cause calls to be dropped and car navigation to fail. On the other hand, devices must look appealing and their size must be minimized. The thinness of the devices and the presence of metallic structures have caused challenges to antenna design. Without 3D simulations, there is a high risk of having poor antenna performance or clumsy industrial design. The alternative for antenna verifi cation is to use multiple prototyping rounds, which are expensive and have a long lead time. However, there are things that cannot be effectively studied with prototypes, for example grounding structures and impedance matching networks. Read full article..

Airbus Defence and Space Uses CST STUDIO SUITE to Analyze Antenna Systems on BepiColombo

Airbus Defence and Space Uses CST STUDIO SUITE to Analyze Antenna Systems on BepiColombo Document type
BepiColombo is a joint mission of the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA). The aim of the mission is to send two orbiters to Mercury in order to study its atmosphere, composition and magnetic field to help understand how the planet was formed, as well as to verify some key predictions of general relativity. Airbus Defence and Space (Airbus DS) is the prime contractor for the ESA elements of the mission, including the Mercury Planetary Orbiter (MPO). The MPO includes multiple antenna systems – some of which are moveable – for telemetry, tracking and control (TTC) and scientific purposes, mounted on a single satellite bus, along with solar panels and instruments which can obstruct the antennas themselves (Figure 1). In order to ensure that the MPO functions as expected when it reaches Mercury’s orbit, Airbus DS has to investigate any possible issues that could affect antenna performance across all of the spacecraft’s different configurations.

8th Order Dielectric Resonator Filter with Three Asymmetric Transmission Zeroes

8th Order Dielectric Resonator Filter with Three Asymmetric Transmission Zeroes Document type
The dielectric resonator fi lter (Figure 1) is a high-performance filter design which is well-suited for applications where compactness and power are important. These sorts of filters are widely used in communication systems – for example, in mobile phone base-stations. The number of independent design parameters that need to be optimized makes higher-order dielectric resonator filters challenging to tune. Simulation software can therefore be used to make it easier to design and tune these filters. Read full article..

"Leaky" Cables Make Fine Broadband Antennas

"Leaky" Cables Make Fine Broadband Antennas
A cable that leaks electromagnetic energy sounds like a defective cable. Yet, ironically, it makes an excellent broadband antenna. To avoid confusion, antennas based on this approach are called leaky feeders. They are typically used in environments that mirror the cylindrical shape and length of the cable: tunnels, mines, aircraft, railroad tracks and skyscrapers. CST provides a tutorial explaining the basic theory and electromagnetic performance. Turning theory into practice, with assistance from W. L. Gore, we examine their use enabling Wi-Fi and cellular service on commercial airlines and corporate jets. Read full article..

RF Breakdown Analysis in Space Applications

RF Breakdown Analysis in Space Applications Document type
Devices in the output section of a satellite payload, including filters and multiplexers are subject to high RF power. This could lead to RF breakdown, which may render the specific device useless and, in the end, degrades the reliability of the satellite. Therefore all space high power devices have to be analyzed with regards to their breakdown behavior. This application note shows how CST STUDIO SUITE® and SPARK3D® can be used to investigate these effects via simulation. Read full article..

USB 3.1 Type-C Simulation and Compliance Test
USB 3.1 Type-C Connector Simulation and SI compliance tool. With the continued adoption of USB interface, there is a need to adapt the USB technology with the newer devices as they become smaller, thinner, lighter and faster. Several types of USB connector are currently available on the markets, including the Type-A, Type-B, Mini-A, Mini-B, Micro-A and Micro-B. All of these different types of USB connector are by design difficult to insert incorrectly when mating the USB plug and receptacle. Read full article..
