摘要

本文介绍了一种用于无线体域网络的双频双模天线，该天线在低频段（LB）具有全向辐射方向图，在高频段（UB）具有可重构方向图。该天线由负载金属圆形贴片和交叉贴片的单极子、四个可重构寄生元件和一个偏置电路组成。LB中的全向辐射方向图是通过加载交叉贴片和短引脚的单极子来实现的。PIN二极管用于控制圆形贴片周围的寄生元件。UB的辐射波束可导向性是通过在期望方向上选择一个寄生元件作为导向性来实现的。该天线的实测工作带宽为- 10db，分别为2.24 GHz ~ 2.70 GHz（18.6%）和5.13 GHz ~ 5.89 GHz（13.8%）。LB和UB的实际增益分别约为1.95 dBi和6.70 dBi。

Dual-Band Antenna With 2.4 GHz Omnidirectional and 5.8 GHz Pattern-Reconfigurable Radiation Modes

This letter presents a dual-band, dual-mode antenna with an omnidirectional radiation pattern in the lower band (LB) and reconfigurable pattern in the upper band (UB) for wireless body area networks. The proposed antenna is composed of a monopole loaded with a metal circular patch and a crossed patch, four reconfigurable parasitic elements and a biasing circuit. The omnidirectional radiation pattern in the LB is realized by the monopole loaded with the crossed patch and shorting pins. PIN diodes are used to control the parasitic elements around the circular patch. Radiation-beam steerability in the UB is achieved by selecting one parasitic element in the desired direction as the director. The proposed antenna has a measured −10 dB operating bandwidth of 2.24 GHz to 2.70 GHz (18.6%) and 5.13 GHz to 5.89 GHz (13.8%). Realized gains in the LB and UB are about 1.95 dBi and 6.70 dBi, respectively.

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.
