Abstract

Wearable antennas (WAs) are critical to communication among in, on, or off-body devices, and have been designed for a variety of frequency and radiation requirements. However, various factors, such as position and orientation of body, etc., can affect the antenna performance drastically, and consequently cause undesirable radiation behavior. This paper aims at offering a practical solution to the real-time design of WAs for telemedicine. Due to flexibility and high convergence speed of Particle Swarm Optimization (PSO) algorithms, modified binary PSO is utilized to reconfigure a proposed WA in order to maintain resonance at 2.45GHz at different bend angles.

可穿戴天线的实时重构
可穿戴天线(WAs)对于体内、体上或体外设备之间的通信至关重要,并且已被设计用于各种频率和辐射要求。然而,各种因素,如身体的位置和方向等,可以极大地影响天线的性能,从而导致不良的辐射行为。本文旨在为远程医疗系统的实时设计提供一种实用的解决方案。利用粒子群优化算法的灵活性和较快的收敛速度,利用改进的二值粒子群优化算法对所提出的波束进行重新配置,使其在不同弯曲角度下保持2.45GHz的共振。
