Phase center variation<10 mm over elevation/azimuth
Group delay variation in-band10 ns max at each GNSS system bandwidth. Note:Inter-signal requirement 50 ns max.
EMI immunity out-of-band30 V/m
Out-of-band rejection40 dB typ
ESD circuit protection15 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 ?
