cst help

When i simulate monopole antenna with cst. There is a waring:"Port number 1 has very few transversal points to calculate the desired number of modes.This may lead to inaccurate mode patterns." who can tell me what reason causes that. thanks a lot
 

cst help

when you post ur MWS-files(*.mod; *.par), maybe could i help u.
 

cst help

You have very draft meshing (too low cells number) in port region. Increase the meshcells number in port region. But it is not without fail, if You need to take into account only one (main) mode at this port (of course, if You think that the current meshcells number is enough to right calculation of main port mode).

Best regards,

Re: cst help

You didnt choose correct the ground points of the port.
