![]() ![]() In particular, for filter design, CST Studio Suite® incorporates two suitable 3D solvers: It incorporates several electromagnetic field solvers suitable for different applications. In particular, we present two specific workflows, which filter designers can also apply to their own developments regardless the specific technology.īefore describing the workflows to design microwave filters within the CST Studio Suite® environment, we introduce the specific tools and solvers that we will need during the design process.ĬST Studio Suite® is a high-performance 3D electromagnetic (EM) analysis software package for analyzing/designing EM components and systems. In this blog post, we show how to combine different tools and techniques to design filters based on SIW and ESIW technology efficiently. On the other hand, filter design is often a cumbersome task, especially if the filter specifications are challenging. ![]() Thus, a circuit with low losses, fully integrated in a planar substrate, can be developed. This approach enables the direct access of the waveguide to the microstrip line. More recently, some authors have proposed a technology based on waveguide technology that is compatible with integrated planar circuits, the so-called empty substrate integrated waveguide (ESIW). This technology is a good trade-off between the benefits of waveguides, having low losses and high power handling capability, and planar circuits, offering tight integration and low cost. Over the past two decades, substrate integrated waveguide (SIW) technology has been used to develop filters at high frequencies. ![]() The function of such a device is to filter a signal’s spectrum, generally while also maintaining the integrity and avoiding thermal noise and unwanted interference. Most modern wireless systems require electromagnetic (EM) filters: cellular base stations, satellite telecommunications, radar systems, etc. We apply these workflows to the design of filters based on Substrate Integrated Waveguide (SIW) and Empty Substrate Integrated Waveguide (ESIW) technology. In this blog post, we show how to combine different tools and techniques within the SIMULIA CST Studio Suite® environment to design microwave filters. ![]()
