Recently, portable telecommunication devices have been equipped with various wireless communication functions. Consequently, the user has come to be able to access various information networks with those equipments. At the same time, the wearable computer technologies have been also researched actively. In the wearable computing, information is transmitted across the wireless applications worn on the clothing. The mobile communication is inferior to the motionless communication at both transmission rate and information amount. However, a recent technical improvement has succeeded to improve transmission rate greatly in the short distance. In fact like that, there has been much attempt to realize broadband communication by wearable technologies. On the other hand, the antenna is indispensable existence to the wireless communication system. Furthermore, because the wireless communication system had become a familiar item, the antenna came to be used in more the vicinity of the human body. By the way, antennas are ever needed for only wireless applications, but there will be increasingly several cases that they are used near human body. The antenna performances are badly deteriorated near human body. Hence, so wearable antenna, which has good characteristics in this situation is not ever little reported. Therefore, in this report, we will provide one prototype of the wideband wearable antenna for terrestrial digital broadcasting.
