MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202647033282 A) filed by Google LLC on March 19, 2026, for Foldable Electronic Device With Detune Elements Integrated In An Nfc Antenna Loop For Controlled Antenna Decoupling When Closed.
Inventors include Yang, Zhenchao; Asrani, Vijay L.; and Li, Pei.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: A foldable electronic device (102) comprises a housing (104) having a first housing section (112) and a second housing section (114) connected by a movement structure (116), such as a hinge, allowing the housing to rotate between an open orientation, in which the facing surfaces (120, 124) of the housing sections are substantially coplanar, and a closed orientation, in which the surfaces (120, 124) are substantially parallel and positioned on the same side of the movement structure (116). One or more display modules (106-1, 106- 2, 106-3) are arranged on one or both housing sections (112, 114). A plurality of antennas (306) are located along a first bezel (304) of the first housing section (112). A plurality of detune elements (134) are disposed along a second bezel (308) of the second housing section (114) and are configured to influence or detune the resonance of the antennas (306) when the device (102) is folded. The detune elements (134) are further incorporated into a near-field communication (NFC) antenna loop (136) positioned on the second bezel (308), enabling NFC transmission and reception. By electrically coupling the detune elements (134) with the antennas (306) through the housing geometry, the foldable device maintains stable antenna impedance, reduces electromagnetic coupling between the housing sections, and preserves reliable NFC communication efficiency in both the open and closed states.
