摘要
本文提出了一种双宽带微带天线，该天线采用叠加结构设计，与单层衬底设计相比，具有更好的带宽。所设计的开槽堆叠贴片天线可以在Wimax (2.2-3.4 GHz)、WLAN (2.40- 2.48GHz)和UMTS II (2.50- 2.69GHz)频段工作，最大带宽为37.95%。空气用作两层之间的电介质，两层之间保持10mm的高度。设计中采用的馈电技术为同轴探头馈电，并利用基于MOM的IE3D对结构的阻抗匹配和辐射特性进行了研究。仿真结果表明，该天线在Wi - Max和WLAN应用中具有良好的性能。
Dual Wideband Stacked Patch Antenna for WiMax and WLAN Applications
This paper presents dual wideband microstrip antenna which is designed using stacking configuration to give a better bandwidth as compared to single layer substrate design. The designed slotted stacked patch antenna can operate in the Wimax, (2.2-3.4 GHz) WLAN (2.40--2.48GHz), and UMTS II (2.50--2.69GHz) frequency band giving a maximum bandwidth of 37.95%. The air is used as a dielectric between the two stacks and a height of 10 mm is kept between the two stacks. The feeding technique used in the design is the coaxial probe feed and the impedance matching and radiation characteristics of the structure are investigated using MOM based IE3D. The simulation result shows that the proposed antenna can offer excellent performance for Wi Max and WLAN application.
