6.2.2. Sharky uFL Antenna
The Sharky uFL antenna module has no particular requirements for board placement.
Keep the large metal objects away from antenna to avoid electromagnetic field blocking.• Do
not enclose the antenna within a metal shield.
Keep any components which may radiate noise or signals within the 2.4 GHz – 2.5 GHz
frequency band away from the antenna and if possible, shield those components. Any noise
radiated from the host board in this frequency band will degrade the sensitivity of the module.
Make sure the width of the traces routed to GND, VDD and VBAT rails are sufficiently larger
forhandling the peak Tx current consumption
