随着无线通信网络规模越来越大，移动终端将占据越来越重要的地位，它们必须更加紧凑，其功能也需要进一步发展。天线是无线系统中的移动终端的关键元件之一。薄、轻、紧凑且灵活的天线将有很大的用处。例子有：集成在衣服内的柔性天线（所谓的可穿戴天线），以及以各种配置附着在物体上的柔性 RFID。对于可穿戴天线，提出了一种微带天线，并报告了弯曲情况下的特性[1][2]。一般而言，微带天线被认为需要大面积的接地平面，以便较少受到后面物体（例如人体）的影响。背腔缝隙天线（CBSA）[3][4]也可以具有几毫米厚的薄结构。报道了一种由铝箔和聚苯乙烯泡沫组成的柔性 CBSA，并显示了弯曲天线的辐射特性 [5]。由于 CBSA 有背腔，因此被认为对背面的物体不太敏感。在本文中，CBSA 采用导电织物制成，并被验证为可穿戴天线。
As wireless communication networks are growing larger and larger, mobile terminals would take more important part, and they have to be more compact and their functions should be further developed. An antenna is one of key elements in such mobile terminals in wireless systems. Thin, light weight, compact and flexible antenna would be of great use. Examples are; a flexible antenna integrated within clothing (so called a wearable antenna), and flexible RFIDs attached on objects in various configurations. As for a wearable antenna, a microstrip antenna was proposed and the characteristics were reported in the case of being bent [1][2]. Microstrip antennas are, in general, considered to need a large area of the ground plane so as to be less affected by an object behind, for example a human body. A cavity backed slot antenna (CBSA) [3][4] is also able to have a thin structure of a few mm thickness. A flexible CBSA consisting of aluminium foils and a polystyrene foam was reported and the radiation characteristics from the bent antenna are shown [5]. CBSAs are considered to be less sensitive to objects in the backside because of their backed cavity. In this paper, a CBSA is fabricated with a conducting fabric and verified as a wearable antenna.
