`` Антенна Бестера после Harry36 ...

I'm glad you like my antenna.

You are wrong with the choice of the disk size. Antenna SWR with optimal dimensions should not exceed 1.15

For example, here are two calculations, the first in FD and the second in TD. And in HFSS

[Admin 2545]

,,, then try to transposes this type of antenna on the frequency range 1.7-2.7 GHz...!!!

[Admin 2545]

,,, with this type of connector ...

I adapted this Bester antenna....

And here is the connector file for those interested....

sma 5110CC.cst

,,,and BesterM Antenna...

This type of connector is not suitable for the model's dimensions.

,,, wrong, look at the calculation once again .... !!!!

I don't need a calculator to add 3 numbers.

[Admin 2545]

,,, yes, I see that you are on the right track, I didn't understand what you meant before, why is not the suitable connector ... ?? ... !!!

If you cut Teflon (0.6 mm) or place a washer under the back of the reflector, you can use the SMA-09V4-TGG connector.

,,,,yes, but the same can be done with my connector above...!!!

,,, okay, you can make a   * cst file with this connector...???

 

[Admin 2545]

,,yes, it's true, the distance between directors and the diameter of the directors, it would be best, I  think it is Lambda / Pi = 0,318*Lambda...!!!

 

[Admin 2545]

I think these Bester antenna sizes ensure a higher bandwidth

,,, or with 12 elements...

[Admin 2545]

,,,for which this antenna variant is also very good ... ???

 

[Admin 2545]

,,,an antenna with square elements cut corners...

[Admin 2545]

,,, and for the 1800MHz frequency...

nice job jomy  for 1800 mhz it will gives  good isolation for x polarisation  or  needs  to be recised ?

,,, it might work, but the isolation between ports leaves much to be desired, it must be tried ... !!!
