This letter presents two designs of pattern-reconfigurable wearable antennas for body-centric wireless communications (BCWC). The reconfigurabilities of these two designs are realized utilizing two totally different mechanisms. In the first design, two subantennas with different radiation patterns are integrated. With a reconfigurable feeding network, the design can switch between the two subantennas. In the second design, the antenna's internal structure can be reconfigured to perform different radiation patterns. Measured results verify that both antenna designs provide reconfigurable omnidirectional and directional radiation patterns.

用于体心通信的模式可重构可穿戴天线设计

这封信介绍了两种用于以身体为中心的无线通信 (BCWC) 的模式可重构可穿戴天线设计。这两种设计的可重构性是利用两种完全不同的机制实现的。在第一种设计中，集成了具有不同辐射模式的两个子天线。通过可重新配置的馈电网络，该设计可以在两个子天线之间切换。在第二种设计中，可以重新配置天线的内部结构以执行不同的辐射模式。测量结果证实两种天线设计都提供可重新配置的全向和定向辐射模式。
