hi friends
I have designed Unbalanced mode spiral antenna backed by an extremely shallow cavity model using CST MWS 2009.
I don't know what that means unbalanced and balanced mode.
I have attached my model but i don't know whether it is unbalanced or balanced..plz help to identify.....
I want to know how to get R VS frequency, X VS frequency and radiation patters for UnBALS and BALS in figure 5, Current VS arms distances, AR VS frequency and Gain VS frequency?
Plz guide me to these graph in CST 2009.
when i simulate this model in CST MWS 2006, i got this error:
" The solid absorber 1: solid 3 within the region of port 1 has very high losses. The accuracy may be degraded in this case."
" Not enough transversal points for port 1 to calculate the desired number of modes"
Why this model has different result for different version.
I have attached word file of this model resuls which was designed in CST 2006.
Thank you
