Lighter GPS Antenna for NAVIO 2

I’m building a very light quad and is looking for the smallest and lightest GPS antenna I can use with NAVIO 2

The supplied antenna https://emlid.com/shop/gpsgnss-antenna-mcx/ is kind of big and heavy.

What data should I look for? Any suggestions to what I can use?

Look for active antennas that can handle 3.3V power supply. Helix antennas should fit, as well as smaller and thinner ceramics without a case (just not too small).
