Obtaining the Dual Antenna Unmatched S-Parameters

Solve the dual PIFA antenna and obtain the unmatched S-parameters.

Follow the same steps as for the previous model.

• Create a new CADFEKO model.
• Import the antenna model for the dual_antenna.dxf file.
• Use the same approach as the previous model.
• Place wire ports at both feed pads of the dual antenna.
• For the S-parameter request, ensure both ports are active.
