摘要

如今，天线实际上通常被用作生物医学应用的一部分。提出了一种工作在2.45GHz工业、科学和医疗无线电(ISM)频段的紧凑型开口槽馈电微带天线，用于生物医学应用中不引人注意但合理的身体通信。为了减少微带损耗和固有匹配，该天线采用了开口槽馈电，为了减少相互耦合效应，采用了缺陷接地结构。因此，实现了高增益(7.2dBi)和宽阻抗带宽(16%，中心频率2.45GHz)，消除了以往工作的所有限制。在2.45 GHz时回波损耗值为- 46.64 dB。在三层人体幻影模型中分析了天线的整体性能。CST(计算机仿真技术)微波工作室成为设计和模拟天线。

Design and Overall Performance Analysis of an Open End Slot Feed Miniature Microstrip Antenna for On-body Biomedical Applications

These days Antenna is in effect generally utilized as a part of biomedical applications. A compact open end slot feed microstrip antenna working in Industrial, Scientific and Medical radio (ISM) band at 2.45GHz is proposed for on-body communications which are not obtrusive but reasonable for bio-medical applications. The antenna consists of an open-end slot feed in order to reduce microstrip losses and inherent matching and defected ground structure in order to reduce mutual coupling effect. As a result, high gain (7.2dBi) and a wide impedance bandwidth (16% with a center frequency 2.45GHz) are achieved which remove all limitation of the previous work. The magnitude of return loss is found −46.64 dB at 2.45 GHz. The antenna overall performance is analyzed in a three-layer human phantom model. CST (Computer simulation Technology) Microwave Studio become used to design and simulates the antenna.
