Antenna Port

The EMA3D Antenna Port tool allows users to define an antenna port for use in S-parameter simulations.

Instructions

  1. After the Domain is set, clickantenna port 16 Antenna Port within the Excitations section under the EMA3D tab in the ribbon.

    2. Antenna port 1

  2. In the Properties Panel, adjust the antenna port properties as desired.

    3. Antenna port 2

  3. Using the select surfaceSelect Surface Image 16 tool, select the surface to which to assign the antenna port definition. It will be immediately recolored blue.

    4. Antenna port 3

  4. Click OKCheck Image 16 to complete the antenna port definition. The current or voltage source will appear on the Antenna Port surface with an arrow denoting its direction.

    5. Antenna port 4

  5. Adjust the definitions of the antenna port at any time by right clicking it within the Simulation Tree and selecting Edit from the pop-up menu.

  6. Mesh the model. To start an S-parameter simulation with the Antenna Port, select theSPort Image 16 S-parameter analysis button within the Analysis section under the Analysis tab within the EMA3D tab. Once complete, various analysis options are available by right clicking the S-parameter results output within the Results node of the Simulation Tree.
