Wideband Wearable Antenna

Recently many kinds of wireless communication systems are provided. And some kinds of their services are usable at any place in the urban area, for example, mobile phone, wireless LAN and etc. On the other hand, their terminals tend to be compact and their antenna sensitivities also tend to be degraded. But the antenna is the most important key device in order to achieve the high speed data communications. In this trend, we think the wideband wearable antenna which is usable for multi-applications is one of the strong candidates in the next generation device [1][2][3][4]. This time, we tried to develop the wideband wearable antenna applicable for the specified low-power radio usable in 400MHz band and receiving the digital television broadcasting wave from 470MHz to 770MHz as the initial approach. Our approach for the wearable antenna was mainly implemented by the experimental work and the good results were obtained. This paper introduces its antenna construction, the return loss performance in some effective situations and the results of the receiving test for the broadcasting wave.
