Abstract:

Nowadays emerging 5G and IoT service scenarios boost a new era of wireless communication technology, which leads to an urgent necessity of developing a new class of hardware and software technology. Without doubt, mobile terminal and base station are two typical hardware packages to provide mobile communication services. Recently, new classes and different scales of hardware prototypes for base station and mobile terminal are being suggested and tested. In such prototypes, antennas have been an essential instrument but occupied the largest volume among wireless components due to fundamental limit of efficient radiation. I will first present existing 4G antenna topologies and operation principles in bases station and mobile terminal, and then attempt to compare the emerging 5G antenna technology to 4G. Finally, I will discuss about new opportunities of future antenna technology from the aspects of academia and industry.
