Yagi-Disk antenna for 2350 MHz

[dumser2 18]

I need your help, namely:
calculations are needed Yagi-Disk antenna for 2350 with a band of at least 100MHz at 50Ω

Directional polarization is required

Types of Polarization:

Linear Polarization

Circular Polarization

Elliptical Polarization

Yes, it's not bad, but SWR needs to be <1.2. Also, if possible, if it improves the result, increase the number of disks.

It is possible to get a drawing or *cst file, I will try to do it.

[Admin 2578]

,,, better try to simulate it yourself...!!!

Yes, I will try, thank you very much. I will show the result.

[dumser2 18]

I seem to be doing something wrong. Can you still reset the cst file?

 

[Admin 2578]

,,,this is not possible, it's a mistake in the SMA plug (the connection between the plug and the vibrating disc)>>>!!!!

,I will send you the cst file"

[dumser2 18]

Is there any example of how to connect it correctly?

S1.1 is out of range

[Admin 2578]

S11 or VSWR indicates the amount of energy reflected in the RF circuit and transmitted to the antenna. The smaller the value, the better it is. Generally, S11≤-6dB or VSWR≤3 would indicate acceptable performance.

[dumser2 18]

Rate the work!

,,,the antenna looks very good but it would be interesting to see its feed points  (inside)...!!!

[dumser2 18]

Unfortunately, I already gave the antenna away.
