wideband antenna meaning in English
宽频带天线
Examples
- The circular monopole antenna is a kind of miniaturized and easy - feed ultra - wideband antenna
本课题所研究的圆盘单极天线是一种小型化、馈电简单的超宽带天线。 - At last , two circular monopole ultra - wideband antennas with different radius are made . by experiments , the return loss , radiation pattern and gain of the
最后,本课题实际制作了不同尺寸的圆盘单极超宽带天线,分别测量了天线的反射损耗,方向图和增益,并与仿真结果加以比较。 - As a result , the ultra - wideband antenna must be able to radiate and receive the short pulse signals without distortion , in other words , the ultra - wideband antenna has to own several octave impedance bandwidth or more , and stable phase center , which enables the ultra - wideband antenna to transmit and receive short pulse signals without distortion
这就要求超宽带天线具有辐射和接收时域短脉冲信号的能力,即拥有几个甚至十几个倍频程的阻抗带宽,同时天线应具有稳定的相位中心以保证不失真地收发短脉冲信号。 - The research in software radio is not more than ten years , but has made a great many fruits , but it is too little to set up an integrated theory system , and software radio includes many areas such as modern communication system ( which includes modem source / channel encoding and decoding , equalization , encrypt and decrypt and so on ) , wideband antenna theory , digital signal process , microelectronics , computer and so on . this thesis mainly does research for modem in modem communication
软件无线电经过不到10年的研究，尽管取得了很多成果，但是对于建立一套完整的理论体系来说，还远远不够，况且软件无线电涉及的领域多、面广、发展快，如现代通信理论(含调制解调、信源信道编解码、均衡、加密解密等) 、宽带天线理论、数字信号处理、微电子、计算机等。 - Firstly , the differences between the ultra - wideband antenna and conventional wideband antenna are introduced in this thesis , and the definitions of several performance parameters of the ultra - wideband antenna are presented , among which the phase center and the group delay time are primarily discussed in that they describe the time domain properties of the antenna
首先,简要介绍了超宽带天线与传统超宽带天线的区别,给出了超宽带天线的性能参数在时域的描述方法。着重介绍了描述超宽带天线时域特性的两个参数,即相位中心和群延时。
