摘要

设计了一种应用于GSM850/900/GPS/DCS1800/PCS1900/UMTS2100多频段移动通信制式的紧凑型手机内置环形天线.整个天线结构包括一个弯折线形的折叠环形辐射体和T型背面耦合单元，其中环形辐射体由连接至微带馈线的T型单元通过电磁耦合机制激励.整个结构尺寸为114 mm×61.6 mm×6 mm，其中环形辐射体仅占空间61.6 mm×15 mm×6 mm，结构紧凑，适合满足移动手机狭小的空间要求.使用HFSS仿真软件设计和优化天线，并构建一个实际的测试模型.测量结果和仿真结果吻合良好，表明此天线能够满足实际需求.

Abstract

The design of a compact internal multiband folded loop antenna for GSM850/900/GPS/DCS1800/PCS1900/UMTS2100 multiple mobile operation has been proposed. The whole antenna structure consists of a single folded meander loop track and a T-shape back-coupling element

whereas the loop pattern is activated through the electromagnetic coupling mechanism by the T-shape element which is connected to the microstrip feeding line. The size of the total structure is 114 mm×61.6 mm×6 mm

meanwhile the area left for the loop track is only 61.6 mm×15 mm×6 mm. The compact structure makes the design very suitable for the mobile phone requirements for slim space. The design and optimizing of the performance of the proposed antenna were performed by using the simulator software HFSS. An actual model has been prototyped for testing. Measured and electromagnetic simulated results are in good agreement

thus indicating that the proposed antenna can meet the actual demands.
