The SIMULIA Community is our user forum for all those interested in simulation of structures, fluids or electromagnetic fields. You can download the Antenna Magus Learning Edition free of charge from the SIMULIA Community. All simulation models generated using Antenna Magus Learning Edition are fully compatible with CST Studio Suite and some models are also compatible with CST Studio Suite Student Edition It can also be used to synthesize basic antenna arrays and includes a selection of useful utilities. Many additional tools and utilities useful for efficient antenna and array design or evaluation are also included.Īntenna Magus Learning Edition makes design capabilities for 12 popular antenna types available and can generate high quality simulation models of these designs. It supports over 350 antenna types, which can be designed to meet the system criteria and exported to integrate seamlessly with your design workflow. The volatge used is 1 and input impedence is 50 ohm.Antenna Magus is the most extensive antenna synthesis tool available today.

So, in comsol, I am using lumped port as shown in attached file. I don't know where is wave port in comsol.

As you can see in the diagrams, the wave port is somewhat floating in the air.

The only difference that i can see in both the models is this wave port used in CST, shown in the attached file. However, in comsol its very different (S11= -15dB, directivity spread all side). Just to highlight again:- My problem is, i am using the same parameters to model an antenna in comsol and CST, the results (S11 = -20dB, directivity in particular direction) obtained in CST are good. I have attached the microstrip patch antenna model made in comsol and CST below. I have looked around application library of comsol multiphysics but all the examples there are using either lumped port or port boundary condition for exciting the antenna. Could you please guide me in where i can see these (boundary mode calculations) examples?
