Portable electrical device

摘要

A portable electrical device including an antenna radiation body, a wireless communication module and a cable is provided. The antenna radiation body transceives a first radio frequency (RF) signal belonging to a first frequency band. The wireless communication module processes the first RF signal. The cable connects the antenna radiation body with the wireless communication module to transmit the first RF signal. The cable has multiple grounding points. The distances between the neighboring grounding points are less than a quarter wavelength of a signal corresponding to the first frequency band.
