Based on the analysis and investigations of dual-band microstrip annular ring slot antenna, a novel miniaturized dual-band annular ring slot antenna for WLAN applications is presented. It utilizes two rectangle notches to overcome the problem of resonant effects caused by the distance between inner and outer ring slots.

基于对微带双圆环缝隙天线的研究与分析，通过连接型矩形槽设计克服了内、外环距对谐振效果的影响，提出了一种应用于无线局域网通信的小型双频圆环缝隙天线，并且可以实现圆极化。

Control theory of antenna array uses the range-barycenter formular which US Boing put forward in 1970s in radio frequency simulation. This method neglects the change of polarization that the array surface curvature causes and the spacing between the antenna elements, so big errors are made.

射频仿真暗室天线阵列的精度控制通常采用20世纪70年代美国波音公司提出的幅度重心公式，该表达式忽略了天线阵面弧度对三元组喇叭极化方式的影响，以及三元组天线单元间距对控制精度的影响，因此存在控制误差。

A duplexer separates an RF signal received from the built-in dual band antenna from an RF signal to be transmitted to the built-in dual band antenna.

双工器分离从内置双频带天线接收的无线电频率信号和要发送到内置双频带天线的RF信号。

SCR-521. The most significant improvement in the ASE was the use of an antenna duplexer, which permitted the use of just one send-receive antenna, rather than two separate units.

ASE上最重大的改进的使用了天线双工机，使得可以只使用一个收发天线而不是两个，这使飞行时的风阻明显减少，飞行性能得到显著的提高。

Tofind a target and determine its position,any radar station has to basically consist of a transmitter,a receiver,an antenna,an antenna duplexer,a display and a timer.

为了要发现目标和确定其位置，任何雷达站基本上都必须包括发射机、接收机、天线、天线转换开关、显示器和定时装置。

A controller processes the RF signals received at and transmitted from the duplexer and controls the whip antenna driver to extend the whip antenna in a speech state or upon a call attempt from a user.

控制器处理从双工器接收的RF信号和发送到双工器的RF信号，控制拉杆天线驱动器，以便在谈话状态下或一旦用户尝试呼叫时，伸出拉杆天线。

SCR-521. The most significant improvement in the ASE was the useof an antenna duplexer, which permitted the use of just one send-receive antenna, rather than two separate units.This yielded appreciable improvement in aircraft performance because of drastically reduced wind drag.

ASE上最重大的改进的使用了天线双工机，使得可以只使用一个收发天线而不是两个，这使飞行时的风阻明显减少，飞行性能得到显著的提高。

This hybrid antenna consists of a CPW-fed inductive slot antenna and three different shapes (I-, L-, and F-shaped) of the dual monopole antennas.
