Abstract

An apparatus comprising: a ground plane configured to receive an antenna, operable in a first resonant frequency band, at a first end of the ground plane; and a member configured to electromagnetically couple with the antenna, provide the ground plane with an electrical dimension, in combination with the antenna, having a resonant mode at the first resonant frequency band, and to reduce current distribution at a second end of the ground plane, different to the first end.

Description

technical field [0001] Embodiments of the present invention relate to an apparatus, method and computer program for wireless communication. In particular, they relate to an apparatus, method and computer program in a portable electronic device. Background technique [0002] Devices such as portable electronic devices typically include one or more antennas for wireless communication with other such devices. The antenna is typically arranged to receive an encoded radio frequency (RF) signal from the transceiver and to transmit the signal to another device. Similarly, an antenna is typically arranged to be able to receive an encoded radio frequency signal from another device and provide the signal to a transceiver for decoding. [0003] In operation, radio frequency signals emitted by the device may affect other electronic devices located in relatively close proximity (eg, within ten centimeters) to the device, that is, the 'near field' of the device may affect other electron...
