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.

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.

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.
