hi friends
I have designed "Divided two arms spiral slot antenna fed by coplanar waveguide using the different magnetic phase different" using CST 2006.
I have attached the word document which has the result in CST 2006.
I have attached the model (which was simulatedin CST 2009)here but it shows different S(dB) VS frequency from CST 2006.
In the model i used two ports to fed the antenna but in the paper,... they have used coplanar waveguide feeding...
how to design coplanar wave guide feeding?
Plz tell me how i can get the figure 4, figure 5 and figure 6 in CST.
When i simulate using CST 2006, there are two erros:
1... 1 propagation mode at port 1 is not considered in time domain calculation! (1 mode shares the same beta with considered modes...> degeneration). It might be better to increase the number of modes at port 1.
2....The calculation seems to be unstable !. consider reducing the value for the stability factor in the solver special options or reducing the PBA fill limit in the automesh properties.
why is it showing these error?
in the paper,
they gave only antenna size W x L x H
using this details how we can get the inner radius, outer radius of spiral , width of spiral and spacing between two arms....?
Is there any equation to find these parameters?
thank you
