Hi,

Lately, I was doing a little research on designing a GPS antenna on a PCB.

Just like with 2.4 GHz Wifi and BT antennas, I was thinking that I would find at least few reasonable app notes from tech giants including formulas, templates, layout examples etc...

But all I find is either GPS modules or GPS antennas that are already manufactured and out for sale...

What if I want to design a GPS antenna directly embedded into my PCB? Internet is full of online PCB patch antenna calculators and I have all the data for it (50 ohms, RHCP, 1575 MHz, FR4...). Would an antenna designed in such way work? Or is there a serious reason why any 1575 MHZ antenna wouldnt work and you cant find design notes just like that

 

There the most time saving method would be to etch what designed and add the SA1201 (up to 2.7 GHz) or alternatively nanoVNA (up to 6.3 GHz). Actually, N1201SA is more simple in use.
