DIY GPS, WiFi, BT antenna question

[slack]

I have a tablet (Goclever M713G - GPS, BT, WiFi, FM processor used in this unit is MT6620) which performs poorly in GPS reception.
The antenna (alu foil) integrated in tablet is used for GP, WiFi and BT.
WiFi, BT reception is OK but GPS reception is  poor.
If tablet used separate antenna for GPS I would buy ceramic patch antenna and solve GPS reception problem.
So I want to make an antenna that would perform better in GPS range, but I would not want to loose WiFi and BT.
I found this document (see attachment) about a GPS antenna that could be easily made at home and I am planing to make it and put it in my tablet instead of original antenna, to see if GPS reception is improved.
Did someone of you guys make GPS , WiFi, BT antenna that performs OK, I searched web but I could not find DIY project for such antenna.
I also want to try re-radiating GPS antenna.
I am looking for ideas on integrated GPS, WiFi, BT antenna.

I suspect the radio front end in your Crapceiver MT666G-whiz may make the antenna effort not be worth the trouble, and you would be better off putting in an LNB. But that kills the WiFi if you use a tuned amp, and likely kills the GPS with noise if broadband.

Like people, it'll do one thing well (MAYBE), or many things poorly, is my prediction.

And you do realize that with the time you spend on this, you can buy a top of the line aircraft GPS radio

Then again, you can always just step outside

Finaly I made a re-radiating GPS antenna, that resolved all problems regarding bad GPS reception.
GPS navigation now works great.
