Wireless devices such as mobile phones rely on the radio spectrum to send and receive data. There is growing interest in using a worldwide unlicensed spectrum around 60 gigahertz for future wireless applications, but conventional ceramic chip antennas have limited performance at this frequency. Junfeng Xu and Xianming Qing at the A*STAR Institute for Infocomm Research and co-workers have now developed a ceramic chip antenna that exhibits stable performance in this spectrum. The antenna has a relatively wide bandwidth of 17.1% and a gain of up to 22.1 decibels.
