血小板免疫荧光测定
Examples
- Pifa ( planar inverted f antenna ) , which has low profile , small size , easy to design and manufacture and many other advantages , is widely used in mobile communication
平面倒f天线( planarinvertedfantenna ,以下简称pifa )具有低剖面,体积小,易于设计制作等优点,在移动通信终端设备中被广泛应用。 - Then analyse the feature of mems switch and gives a equivalent model of cantilever mems switch to analyse its characteristics . at last , a mems multi - frequency reconfigurable pifa is designed and simulated
之后对mems开关进行了研究,并给出了悬臂梁式mems开关的仿真模型,利用此模型分析了各参数对于mems开关传输特性的影响。 - In this thesis , first , the transmission character and radiated character of pifa is analysed , then a equivalent model of pifa is built by cad software to analyse the effect of each dimension of the pifa to the characteristic of the antenna
本文首先根据pifa天线的等效模型对其传输及辐射特性进行了分析研究,并使用计算机仿真软件建立了pifa天线的电磁仿真模型,研究各个参数对于pifa天线特性的影响。 - Antenna parameters studies are presented and practical design considerations for achieving high gain and wide bandwidth are given . in chapter 4 , a novel pifa with high radiation efficiency is designed for a tri - band mobile handset application
天线印刷线路板的尺寸等参数对天线谐振频率和带宽的影响在本章中详细研究,一个详细的实际设计例子也在本章中介绍,测试结果表明天线获得了较高的增益和较宽的带宽。 - The gain of the mems frequency reconfigurable pifa reaches 1 . 5db in all the operation band . since the mems technology has not been used in antenna field widely , the mems frequency reconfigurable pifa in this paper has considerable referenced value to the application of mems antenna
Mems技术现在还没有大规模应用于天线领域,本文所设计的mems频率可重构pifa天线是mems技术在天线领域应用的有益实践,具有一定的借鉴意义。
