[Invited Lecture] A Study of the Antenna Configuration for the 5G Mobile Terminals

Abstract (in Japanese) (See Japanese page) 
(in English) A 28GHz band antenna array is designed for the next generation smartphones. In the fifth generation smartphones, a new antenna will be mounted in addition to the conventional 4G antennas. The new antenna characteristics are required to meet the 5G regulations. Whereas the space for the antenna elements is restricted. We have studied the 5G antenna configuration which can be placed in close proximity to the conventional 4G antenna without deteriorating its radiation properties. A Yagi-Uda antenna array is used as the 5G antenna and an inverted L-shaped antenna is designed as the 4G antenna. The 5G antenna element consists of the radiator and the reflector. Electromagnetic simulation reveals that both 4G and 5G antennas show good performance by tuning the 5G antenna elements position．
