Abstract:
An antenna element forms a ring slot antenna comprising a first slot and second slot. The antenna element is located on a first surface of a conductive chassis that encases a body or a volume for wireless communication signals to be received or transmitted. A coupling component is located on an opposite side of the conductive chassis and behind the antenna element. The coupling component facilitates a coupling between a communication component and the antenna element as a function of the orientation and geometric shape of the coupling component to facilitate different resonant frequencies via the first and second slots of the antenna element.
Abstract:
Described herein are techniques related to near field coupling and WLAN dual-band operations. For example, a WLAN dual-band utilizes the same coil antenna that is utilized for near field communications (NFC) functions. The WLAN dual-band may be integrated into an NFC module to form a single module.
