Antenna mounts
directly above or
below the metal layer
of PCB. No antenna
clearance required
ever again!
Total average radiated efficiency on PCB feature on "Mounting Considerations 1" ( orderable EVB p/n: 2450AT42E0100-EB1SMA) is ~30%
This antenna was designed in mind for small coin cell, wearable, IoT, 2.4 BLE, 802.11, ISM, Zigbee, etc. applications in
close-range networks where metal or a battery/display covers the entire length or side of the PCB or encasement must be
present directly under the antenna and there's no room for usual/typical antenna metal clearance.
