EP112 RF Harvesting Antenna

Harvesting SMD antenna

• Bundled SMD antenna / Adaptation network
• Work in conjunction with high performance PMIC (AEM30xxx family) for RF energy harvesting (RFEH).

Ultra low power start-up 

• PMIC cold starts from 275 mV input voltage and 3 µW input power (typical)
• RF input power from -19 dBm up to 10 dBm (typical)

Compatible with wide transmitter power range

• Linear polarization for higher energy transfer efficiency from emitter to harvester
• Omni-directional pattern for better user experience
• +2 dBi max gain for better performances

Ultra compact design

• SMD antenna design: 10 mm x 2.3 mm x 2.3 mm ceramic device built on glass epoxy substrate
• Compact RX Antenna PCB design (e.g. 132 mm x 61 mm)

Reference design

• EP112 evaluation board (EP112 EVK) comes with complete part list, layout, clearance area, matching network, SMA connector and PCB instructions for evaluation at 900 MHz
• Compatible with any AEM30xxx EVK

Multiple bands

• 863 – 870 MHz / 902 – 928 MHz /

SMD design

• Standard Component re-flow profile (260C peak)
• No complex 3D antenna with metallic inlay

Multiple PCB form factor

• Design optimization for custom size PC
