Question

hello

I dont find at comercial scale small packaged ublox F9P board so I'm planing to design one (https://www.u-blox.com/en/docs/UBX-18010802)

objective is a 25x25 mm pcb with ZED-F9P on bottom layer and antena above 

recomended antena is described below : 

Antenna type	Active antenna
Minimum active antenna gain	17 dB
Maximum active antenna gain	50 dB
Noise figure	<4 dB
L1 band antenna gain	1559 - 1606 MHz: 3 dBic typ.
L2/E5b band antenna gain	1197 - 1249 MHz: 2 dBic typ.
Polarization	RHCP
Axial ratio	2 dB max at Zenith
Phase center variation	<10 mm over elevation/azimuth
Group delay variation in-band	10 ns max at each GNSS system bandwidth. Note:Inter-signal requirement 50 ns max.
EMI immunity out-of-band	30 V/m
Out-of-band rejection	40 dB typ
ESD circuit protection	15 kV human body model air discharge

as I'm not aN extremlly talented RF engineer I try to find something suitable in your products but it could be easier to ask directly if something fits
all active antena I seen on your product pages is requierring at least 40 mm length ground plane witch is a bit to mutch for my footprint needs
can you help me a bit on that product selection phase ?

thank's for any help
