Hi everyone,
I initiated to design a monopole antenna for particular frequency. what are the design considerations of a monopole antenna and what are the available feeding methods to the element. The available software tool for me is CST Microwave Studio Suite.please help me in this regard and i would very thankful to you.
thank you.
Hello Dr. Atchutarao
Can u explain about your design?
if it a simple monopole antenna, u need take a patient when u create this on CST especially on feeding technique, because u need more element "groundplane" on that
i hope this helpfull
Hi
you can see this
http://en.wikipedia.org/wiki/Monopole_antenna
if you mean monopole using path antenna it very simple you can design patch antenna also see youtube examples then finite the ground plane.
If you mean simple wire monopole antenna; its easy;
Draw a vertical wire with radius a and height slightly smaller than (lambda / 4).
Draw a ground plane (circular plane is a good choice) larger than lambda.
Place the Wire (g mm) above ground; g is a gap between antenna and ground plane and is in the order of (lambda / 100).
Excite the antenna with the defining the point source from the center of ground to center of wire antenna
Hi,
You can create a coaxial cable either manually or by using the built in macro with CST MWS, then you can rip the outer conductor and dielectric to the length of the monopole based upon the frequency of the operation under consideration. lambda/4 is a good measure here.

I ask a similar question on a monopole antenna in CST.
I want to check the induced current by a monopole antenna from an external far-field excitation.
How can I model the monopole antenna and how to set the probe(?) for the current calculation?
