Johanson Antenna + On-Semi Bluetooth

Johanson’s Zero clearance, On-ground chip antenna p/n: 2450AT42E010B latest reference design is used in perfect harmony with On-Semi’s BLE beacon chipset, the RSL10, which is the industry's lowest power Bluetooth 5 SoC. This very small, circular reference design gives the designer the advantage of not having to worry what’s directly underneath the Johanson 2.4GHz chip antenna.
