Abstract

With the development of wearable wireless systems and wireless body area networks, the 3.5 GHz WiMAX band has become critical for body-centric communications, creating an urgent demand for high-performance wearable antennas with multifunctional integration, compact size, and stable on-body performance. This letter proposes a novel polarization- and pattern-reconfigurable wearable antenna for the 3.5 GHz WiMAX band. The antenna consists of two square FR-4 dielectric substrates and three metal layers. It can operate in omnidirectional vertical polarization mode and ±45° directional linear polarization modes. It has a compact size of 0.36λ₀ × 0.36λ₀ × 0.035λ₀, with a measured peak gain of up to 7.22 dBi. The antenna maintains stable performance near the human body, and its low specific absorption rate values verify its safety in practical wearable applications.

双可重构极化和方向可穿戴天线

随着可穿戴无线系统和无线体域网络的发展，3.5 GHz WiMAX频段已成为以身体为中心的通信的关键，对多功能集成、尺寸紧凑、稳定的高性能可穿戴天线产生了迫切的需求。这封信提出了一种用于3.5 GHz WiMAX频段的新型极化和模式可重构可穿戴天线。天线由两个方形FR-4介电基板和三个金属层组成。它可以在全向垂直偏振模式和±45°方向线性偏振模式下工作。它具有0.36λ0 × 0.36λ0 × 0.035λ0的紧凑尺寸，测量峰值增益高达7.22 dBi。该天线在人体附近保持稳定的性能，其较低的比吸收率值验证了其在实际可穿戴应用中的安全性。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
