Cross Antenna

[Admin 2421]

The cross antenna is a medium gain and circular polarization structure made of a conductor or a strip line over the ground plane following a cross contour of four or more branches.The construction repeatability is verry easy as well the facility to obtain 14dBi gain in a small antenna.

Can we use this shape for 2.4ghz?

I first time see such a design !!!

with what dimensions?

[Admin 2421]

Yes, it can ... but I can not find the file at this time...!!!

[Admin 2421]

,,,like the 2.4GHz cross-antenna, with a reflector diameter of 240mm...

[aurel 22]

In general ...can we use this dimensions (from colinear antenna) to build this one?

27mm, 6mm, 27mm,

like is on picture?

[Admin 2421]

,,, not, under any circumstances ....!!!

[aurel 22]

ok then which sizes to use ?

Very interesting model! Any generic rule for the design? thanks. I mean explanations.

Could you please explain how the wire ends in this design?

Apart, I understand the wire lenght should be lambda/2. Am I right?

Do you have a .cst file to check the design?

Thanks in advance for your help.
