Abstract

A novel wearable button antenna is proposed for the WLAN applications in 5G technology. The antenna is a button shape Roger substrate (a: 25mm) using a radiator on the top side of a disc, which enhances the users’ comfort and makes it a small size up to date in the literature. Besides, the button is placed on the top side of substrates (Roger, Denim-black) and a conductive ground (copper). Moreover, a superstrate substrate (felt) is used on the top side of a radiator. The main characteristic is showed in three types of radiation patterns, a monopole type in the 2.4538-2.587 GHz for On-body and a broadside in the 5.038-6.03 GHz for off-body communications. Next, the high performance is obtained concerning the gain, bandwidth, and radiation patterns during On-Off body communication, simultaneously. Besides, the lowest specific absorption rate (SAR) is obtained in different bands. Simulated and measurement results are found well. Finally, the effect of the human body is validated using the human hand (hantenna) as an antenna.

面向5G无线局域网应用的可穿戴三波段双模十字形按钮天线

针对5G技术下的无线局域网应用，提出了一种新型的可穿戴按钮天线。天线是一个按钮形状的罗杰基板(a: 25mm)，在圆盘的顶部使用一个散热器，这提高了用户的舒适度，使其在文献中成为一个小尺寸。此外，按钮放置在基材(罗杰，牛仔-黑色)和导电接地(铜)的顶部。此外，在散热器的顶部使用了衬底(毛毡)。其主要特征表现为三种类型的辐射模式，即用于体上通信的单极子类型(2.4538 ~ 2.587 GHz)和用于体外通信的宽边类型(5.038 ~ 6.03 GHz)。其次，在通断体通信期间，同时获得有关增益，带宽和辐射模式的高性能。此外，不同波段的比吸收率(SAR)最低。仿真结果与实测结果吻合良好。最后，以人手(汉天线)作为天线，验证了人体的效果。
