摘要

本文提出了一种工作在2.4GHz的小型、低姿态、可重构天线。该天线具有两个对称的可切换倾斜波束，最大辐射在仰角平面上偏离z轴±60°左右。与全向天线相比，定向天线可以根据传感器的位置改变其波束方向，在能耗、信号灵敏度和较长的通信范围方面都是有利的。所提出的天线可用于身体上的通信，在某些情况下，波束倾斜是必需的，例如在腰带到手腕的路径。分析了天线在自由空间和简化人体组织上方的特性。

Pattern-reconfigurable antenna for on-body communication

A compact, low-profile pattern-reconfigurable antenna working at 2.4GHz is presented in this paper. The antenna exhibits two symmetrical switchable tilted beams with the maximum radiations at around ±60° off the z-axis in elevation plane. In contrast to omnidirectional antennas, directional antennas that can change their beam direction according to the location of sensors are beneficial in terms of energy consumption, signal sensitivity and long communication range. The proposed antenna can be used for on-body communication in some cases beam tilts are desired, for example the paths in the belt-to-wrist. The characteristics of antenna in free space and placed above a simplified human tissue are analyzed.
