Antenna design signal stabilization problem？

[zydxin]

Hello,

Nrf52832 ibeacon broadcast signal is unstable, and the rssi deviation of left and right upper and lower signals before and after the detection of the same distance is about 10-20. Is there any solution to stabilize the signal?Do you have a good antenna design recommendation?

Hi,

RSSI is very unreliable yes, there is no perfect omnidirectional antenna. RSSI will also heavily be influenced by objects or human body/hands that may be be in close proximity to the device(s) or blocking the path.

Best regards,
