Hi,
Has anyone measured performance (efficiency, return loss, peak gain, SNR) of the chip antenna mounted on the NEO-M9N breakout (GPS-15733)? According to most chip antenna manufacturers, the long edge of the ground plane must be around 80 mm to achieve optimal performance. I’m curious to know how (or if) the NEO-M9N breakout, with both edges measuring around 40 mm, achieves satisfactory RF performance.
Thanks!
Unfortunately, we haven’t measured those performance metrics in-house. We haven’t heard of any reported issues regarding these communication metrics in the meantime. We do appreciate the curiosity. Hopefully someone from the community may have experience with this question. Thank you for asking!
I’m curious about how those tests would actually be performed. Would you need an anechoic chamber?
Cheers,
Adam
Yes, ideally a (relatively small) anechoic chamber, as well as a network analyzer, would be needed. Granted, it’s not the cheapest setup! The facilities of some universities can sometimes be rented out though.
