A Multi-Band Antenna in Terminal Device by Machine-Learning Design

This paper proposed a multi-band antenna for terminal devices. A machine learning tool was used to design the antenna in a limited design area. The antenna shows wide bandwidth and high radiation efficiency. It could cover 5 LTE bands range from 1.45 GHz to 3.8 GHz, and no switches are needed. This antenna design is small in size, easy to manufacture, and has high antenna performance. Besides, the design process is high-efficient and takes around 1 week to complete the whole design process. This machine-learning design demonstrate that AI aid design will play a more and more important role in the antenna design process of future terminal devices such as smartphones, smart watches, tablets and so on.
