Hi Kasper,

The standard half-wave dipole comes to mind as it so easily fits into
your available space.

Hi Richard,

thanks for your suggestion,

that means a T-shape as I understand?
The horizontal part should be 2 x 30,7 mm, right?
How long should the vertical line be?
How wide should I make the tracks?
The cable is a 50 ohm coax.

It is a lot simpler than that...

A half wave dipole would be two tracks approx 30.7mm long as you say.
But.. you do not need a vertical line.
Coax can attach directly to the centre point.
Width of the tracks also depends on how much space you have.
The wider the tracks the bigger the bandwidth affected.

Also what may effect the whole installation is the polarisation of the
antenna,
horizontal or vertical.

This depends on the antenna on the other device. Same polarisation
recommended!
