摘要

设计了一种应用于GSM850/GSM900/DCS1800/PCS1900/UMTS2100/LTE 23 GHz/WiMax 25 GHz/LTE 26 GHz多频段移动通信制式的内置单极子手机天线.天线整体结构由单馈电双分支平面辐射体和开槽结构的不完全PCB地组成，双分支平面辐射体能够产生3个谐振点，其中的短分支产生2 600 MHz谐振点，长分支产生900 MHz谐振点，短分支和长分支共同作用产生1 900 MHz谐振点，开槽PCB地延长地板的电流路径，从而降低了低频谐振点，增加天线带宽.天线整体结构尺寸为115 mm×60 mm×6 mm，其中天线辐射体尺寸为50 mm×15 mm×6 mm.所设计的天线结构紧凑、简单，易于制作，满足移动手机天线的设计要求.使用Ansoft HFSS仿真软件设计和优化天线结构，并制作实际的测试模型.实验测量结果和仿真结果一致性较好，表明了此天线结构设计的准确性.

Abstract

It proposes a compact internal multiband antenna with a simple structure for GSM850/GSM900/DCS1800/PCS1900/UMTS2100/LTE 2.3 GHz/WiMax 2.5 GHz/LTE 2.6 GHz multiple mobile operations. The whole structure of the proposed antenna consists of the double strip planar radiation with a single feed and the printed circuit board (PCB) with a proper rectangular slot. The short one of the double strips resonated at 2 600 MHz

while the other resonated at 900 MHz. By the combination of the two strips

they resonated at 1 900 MHz. The slot on PCB could extend the length of the current distribution on the ground of PCB. The size of the total structure of the proposed antenna is 115 mm×60 mm×6 mm; meanwhile

the area left for the antenna is 60 mm×15 mm×6 mm. The simple compact structure makes the design very suitable for the mobile phone. The design and optimizing of the performance of the proposed antenna were performed by using the simulator software Ansoft HFSS. An actual model has been prototyped for testing. Measurement and simulation results are in good agreement

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