An international team of researchers (China, Taiwan) has developed a 28 GHz beam-steering antenna array that can be integrated into the metallic casing of 5G mobile phones. The array antenna has 16 cavity-backed slot antenna elements that are implemented via the metallic back casing of the mobile device, in which two eight-element phased arrays are built on the left- and right-side edges of the mobile device. Each eight-element phased array can yield beam steering at broadside and gain of >15 dBi can be achieved at boresight. The measured 10 dB return loss bandwidth of the antenna element was approximately 27.5–30 GHz. The researchers acknowledge that the beam-steering topologies and algorithms will also have to be developed specifically to meet the stringent requirements of mobile phones… read more. TECHNICAL ARTICLEÂ
