Antenna with dual linear polarizations ? any thoughts ...

[antenna_kid 13]

Hi to all
I'm looking for design of antenna that has:

- wide beam width
- receives horizontal and vertical polarization
- has one port
- gain isn't so important - 5-9dbi will be enough.
- can be made from FR4 (1mm) - I have small CNC so for me it's easiest way.

I know that I can use here antenna with circular polarization - but when will combine linear with circular i will loose 2.6dbi.

I've been looking for such designs but didn't found. 

Cheers

Something like that ...???

yup, it's dual polarized. But it's quite big and has dual port. Looking for something more compact. 
Broad band isn't important for me. More important is wide beam.

What frequency do you want?

[antenna_kid 13]

2.4 and 5.8 but dual polarized mainly for 2.4. Radio (rc control) has one port. That's I'm looking for such design.

I did little research but didn't find something interesting, maybe this one design:

This also looks interesting:

The dual polarized microstrip antenna was design to generate signals with  +45 and -45 polarized but with a loss in directivity gain of about 3dBi

This antenna is more interesting with symmetrical excitation at a resonant frequency

So, we will get almost the same when using CP antenna with similar gain... ?

Something like that!
