  How do I set the port for a structure where the conductor is repeated pointedly as shown in the attached picture?

  Are you intending to set a Lumped Port between the conductor labeled Signal and the conductor labeled GND in the diagram? If so, you should place a Rectangle so that each conductor makes contact at the shortest distance, and then set the Lumped Port.
  Are the translucent objects around each conductor dielectrics? Lumped Ports can be placed even if they interfere with these dielectrics. If you are concerned about this, you can connect sheets with Perfect E boundary conditions set from each conductor, positioning them so as not to interfere with the dielectrics, and then place a Lumped Port between those sheets.
