Total average radiated efficiency on PCB feature on "Mounting Considerations 1" ( orderable EVB p/n: 2450AT42E010B-EB1SMA) is ~35%
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.
This antenna is specifically designed for PCBs that have 1-2mm of total thickness
