The Design and Implementation of Ceramic Antenna for Mobile Terminals of WCDMA System

Abstract

本文主要围绕大带宽、小尺寸天线展开系列研究工作。首先在检索国内外相关领域的最新研究动态和我们研究项目的前期工作基础上,提出了采用高介电常数陶瓷天线与光子带隙结构相结合的手段来设计小型化WCDMA移动终端天线的新方案,完成了实际天线样品的制作,并通过对天线方向图仿真、输入端反射系数等参数的实测优化,进一步完善了此方案的实施技术。论文中实际天线的设计制作还成功地将近年来发展迅速的光子带隙(PBG,PhotonicBand-Gap)技术,应用到了所设计的陶瓷天线接地板上,在谐波抑制、带宽、尺度控制等方面取得了一定进展。陶瓷天线样品尺寸只有3cm×3cm,是普通同频微带天线尺寸的15%,可直接放入移动...Our work focuses on a new kind of antenna with broad bandwidth and small in size. Based on the review of the newest researches tendency in the home and abroad and the prophase studies of ourselves, we propose a new kind of antenna which could be used in WCDMA mobile terminal with a new technique by which combines the ceramic ground plane with high dielectric and the Photonic Band-Gap on it. It has...学位:理学硕士院系专业:信息科学与技术学院电子工程系_无线电物理学号:20043001
