This eSeminar will discuss the application of CST Studio Suite® to a full radar system design.
CST’s complete simulation technology enables the most appropriate method/solver to be applied to the diverse range of components typically found in a radar system. For the digital design, combined PCB/package analysis is necessary to achieve adequate signal integrity and minimize interference/emissions. CST’s transient solver is ideal for capturing the broadband performance of the PCB/package.
On the RF/MW feed system side, different field solvers are put to work for designing and optimizing the various components, including FIT, FEM and MoM. For the antenna element design, unit cell analysis is first applied to simulate an infinite array.
After optimizing at this level, the full (finite) array is simulated using high performance computing techniques enabling the influence of edge element effects and mutual couplings to be understood. Finally, coupling of the antenna back into the feeding cable and electronics can be taken into account using the hybrid 3D field / 2D cable solver technique in CST CABLE STUDIO®.
Tuning of a coupled-resonator filter is performed in this article by using the group delay response of the input reflection coefficient of sequentially tuned resonators containing all the information necessary to design and tune filters. To achieve high...
The example design is a classic hairpin filter with a bandwidth of 3.6 to 4.3 GHz. The hairpin filter was designed for a return loss better than -20dB across the band.
CST DESIGN STUDIO™ was used to design and tune the filter and the resulting layout...
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...
