Mitigation of noise coupling on RF cable using electromagnetic bandgap structures

Abstract

Noise coupling to radio frequency (RF) cable in laptop computers deteriorates the receiving sensitivity of wireless local area network (WLAN) operation. Proposed originally is a concept for reducing noise propagation along RF cable using electromagnetic bandgap (EBG) structures. The proposed EBG structure applied on RF cable allows achieving more than 20 dB noise suppression within the frequency range of WLAN application.
