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 port

a more acceptable result .

any body help ?

thanks!

hi HEE
what is " lange circuit " you mean?
I think you should choose one mode, it is enought for the simulation, if you want to choose two, Hfss will understand that you will have two times of simulation, that mean two set-up, And with the newline, for a normale simulation, keep the defaut without choosing the line of the waveport (use in the case of master and slave port), could you paste the graphic here so we can see more clearly?

hi ,CUONGTRAN

thank you for your help

my design is a lange coupler

i want to simulate it in the HFSS

for network problem , i can't upload my file

i want to add wave port to the coupler , how can it be added in the right way ?



thank you in advance

you should add lumped port! the ansoft calim in its help that it is better!

thank you very much
