Abstract

The invention provides a surface-radiation coupled five-band wearable antenna. The wearable antenna comprises a first radiant surface, second radiant surfaces, a substrate and a ground plate, wherein the first radiant surface carries out feed directly; the second radiant surfaces are grounded to form parasitic short circuit bands, so that the band of the antenna can be broadened; a radiation patch is arranged on the upper surface of the substrate; the ground plate is arranged on the lower surface of the substrate. The wearable antenna has the beneficial effects that the wearable antenna adopts the patch type and button connection, thus increasing the possibility of reconfigurable antennas; the substrate adopts the latex material, thus improving the stability of the antenna during wearing; the wearable antenna has small size, covers five bands, satisfies the need for stabilityto some extent and is applicable at present.

Description

technical field [0001] The invention belongs to the field of antennas, and specifically relates to a five-band wearable antenna with ground-radiation coupling. Background technique [0002] With the rapid development of wireless communication technology and the rise of the wearable device market, wearable electronic communication systems have become one of the current research hotspots. Wearable wireless communication system is an important part of the fourth generation mobile communication, and plays an important role in fields such as physical exercise, medical detection, game experience and security deployment. [0003] The so-called wearable device is a wireless communication device centered on the human body, and its antenna often needs to be bent to attach to the human body or the wearable device. Therefore, in practical applications, improving the stability of wearable antennas is an important point of design. On the other hand, wireless communication devices with m...
