    How to properly add wave port in HFSS?

    for a lange circuit how to add wave port ? first , how i did it assign->wave port->p1->number of modes 2->set newline at the microstrip edge p1(port1)have two modes ,what does mode mean ? two stimulations ? or propagation modes ? i get a bad result i change the wave port to lump...
