Introduction to Designing Microwave Circuits Using EM Simulation
When it comes to designing RF, microwave, and millimeter-wave circuits with electromagnetics simulation, the key is to start simple and gradually add complexity to your analyses.
Introduction to Efficiently Modeling Antennas in COMSOL Multiphysics®
To keep our antenna modeling process efficient and accurate, we should start with a simple geometry and then gradually add more complex features. The final simulation needs to include enough detail to accurately represent our design, while excluding elements that needlessly increase the computational cost. To demonstrate this, we look at an anechoic chamber example, which is used to characterize antenna performance, before examining how this process applies to several antenna examples available in the COMSOL Multiphysics® software.
Methods That Accelerate the Modeling of Bandpass-Filter Type Devices
When designing bandpass-filter type high-Q devices with the finite element method in the frequency domain, you will likely come across a situation where you need to apply many frequency samples to more accurately describe the passband. Simulation time is directly proportional to the number of frequencies included in the simulation of a microwave device, with the time increasing as the frequency resolution used becomes finer. Two powerful simulation methods in the RF Module help accelerate the modeling of such devices.
Optimizing Phased Array Antenna Designs for 5G and IoT with Apps
The 5G mobile network and Internet of Things (IoT) are two hot topics in the RF and microwave industry. New developments in these wireless applications call for much higher data rates, active electronically scanned arrays (AESA), phased array antennas, and multiple-input-multiple-output (MIMO) technology. It is important to reduce the time and cost during the process of prototyping and manufacturing these applications. Using simulation and apps, we can streamline the development cycle of wireless communication designs.
How to Adapt the Real World for Electromagnetics Simulations
In electromagnetics simulations, the ultimate goal is to boost the efficiency and productivity of your device by closely mimicking the effects observed in reality. This process requires an understanding of the reality you are trying to describe and mimic, as well as the details that should be included. Let’s explore the reality of electromagnetic waves with regards to the measurement environment.
How to Create a Simulation App: Horn Antenna Demo
What if you could enable non-experts to run your multiphysics simulations on their own? You would save time, for sure, and they would get easy access to your expertise. Turning your simulations into apps with customized and easy-to-use interfaces is now a reality. Here, I will explain why you should start creating apps and how to go about it. We’ll use the new Corrugated Circular Horn Antenna Simulator demo app to guide us.
