A Transition from CPW to rectangular waveguide simulation using HFWorks for SOLIDWORKS

Article by Nadya Gary updated July 1, 2016

HFWorks for SOLIDWORKS helps designers to size their models to support various designs and various scenarios (multiple configurations), this way user can ensure optimum performance. Another advantage of HFWorks is it’s seamlessly integrated inside SOLIDWORKS, allowing you to run simulations right on your model, without the need for re-importing data with each design modification.

In this example, we propose a transition from CPW to rectangular waveguide centered at 38 GHz.

How does this type of transition work?

It is well known that the main problem in transmission of electromagnetic energy in some media is the effectiveness and the optimality of delivery. This also applies to waveguides since the delivery of electromagnetic energy is often ineffective interfered by the presence of attenuations especially in microwave frequencies.

In order to combine the advantage of CPW  in the excitation method and of rectangular waveguide in the low attenuation. The transition section is applied to convert CPW mode to the dominant modes of TE10 in rectangular waveguide, this structure has  two ports, one port formed by the rectangular waveguide and the other one by the CPW; The return loss is more than 29 dB for air.

HFWorks for SOLIDWORKS helps designers to size their models to support various designs and various scenarios (multiple configurations), this way user can ensure optimum performance. Another  advantage of HFWorks is its seamlessly integrated inside SOLIDWORKS, allowing you to run simulations right on your model, without the need for re-importing data with each design modification.

HFWorks can accurately calculate the insertion loss and return loss, electric field and magnetic field.
