Overview

IEC TR 63239:2020 surveys technologies, product-development trends, international standards and regulatory trends for radio frequency (RF) beam wireless power transfer (WPT) aimed at mobile devices. The report is a state‑of‑the‑art technical overview intended to support research and project analysis for small‑output remote WPT use cases such as smartphones, IoT devices and ultra‑small sensors.

Key topics and technical requirements

RF beam WPT types

Omnidirectional: radiates electromagnetic energy in all directions; lower antenna gain, suitable for short‑range multi‑device coverage.
Directional (beamforming): focuses RF energy toward specific receivers, achieving higher antenna gain but requiring beam steering and line‑of‑sight management.

System design components

Transmitter (TX): microwave power source, waveguide circulator/adaptor, tuner and directional coupler, transmitting antenna (beamforming arrays for directional WPT).
Receiver (RX): antenna, impedance matching and filter circuits, coax‑waveguide adaptor, RF‑DC converter (rectifier) to produce DC power.

Operating principles

Uses radiated electromagnetic waves (unlike inductive or resonant near‑field WPT).
Performance depends on Friis‑type spatial loss, antenna gain, frequency and RF‑DC rectification efficiency.

Candidate frequencies and constraints

Typical candidate ranges: hundreds of MHz to several GHz.
Frequency sharing with existing radio services and spectrum regulation are important considerations.

Safety and regulation

Human exposure limits and safety protections are critical for commercialization. The report summarizes trends in standards and regulatory activity relevant to RF beam WPT.

Practical limitations

Low end‑to‑end efficiency at distance; transfer distances up to several meters are achievable under line‑of‑sight (LOS) conditions for small‑output charging.

Applications

Mobile devices: supplemental or maintenance charging for smartphones and wearables.

IoT and sensors: remote powering of ultra‑small sensors and distributed IoT nodes where battery replacement is impractical.

Multi‑device environments: directional systems can target multiple receivers; omnidirectional systems can support simple multi‑device coverage in short ranges.

Who should use this report

R&D teams and product developers exploring remote wireless charging solutions

System architects designing TX/RX and RF‑DC rectification chains

Regulatory and standards professionals assessing spectrum and safety implications

IoT integrators and infrastructure planners evaluating maintenance‑free sensor deployments

Related standards and trends

IEC TR 63239 documents current standardization and regulation trends rather than normative requirements (the report contains no normative references). It is useful as a roadmap for aligning product development with emerging safety guidelines, spectrum sharing considerations and international standardization activities in RF beam WPT.
