MM-wave phased array antenna for whole-metal-covered 5G mobile phone applications

A novel mm-wave phased array antenna for whole metal covered 5G mobile handset is proposed. The proposed array antenna consists of eight rotated slot antenna elements that are arranged on the upper frame of the metal-body. The proposed array demonstrates good S-parameter characteristics in frequency band ranging from 27.1 to 28.6 GHz and mutual-coupling between antenna elements is less than -19 dB. The proposed array antenna has the hemi-spherical beam coverage suitable for 5G mobile communication.
