- This thesis studies a circularly polarized reflectarray based on a microstrip ring patch as a radiating element. 中文摘要本论文是以环形天线为幅射单元当架构，来研究一圆形极化反射阵列。
- To accomplish time delay scanning, variable delay networks are inserted in front of each radiating element. 要完成时滞扫描，就要把延时网络插入每个辐射单元的前端。
- Only a properly matched antenna system will allow maximum power transfer from the 50 transmission line to the radiating element. 只有一个匹配合适的天线系统才能在发射时使能量充分辐射出去。
- A conclusion can thus be gained that NRD-guide can be used as an UWB antenna and a radiating element of antenna arrays due to small side leakage. 先从频域的角度研究了NRD波导用作超宽带天线时相关参数选择的依据，然后用FDTD方法研究了NRD波导的传播特性以及辐射特性，并与平行板天线的辐射特性比较，得出该天线的突出优点是具有较小的侧向泄漏。
- As the excitation energy travels along the serpentine line, it will reach each successive radiating element with a uniformly increasing positive or negative phase shift. 当激励能量在馈线中传播时，将会在连续相邻的辐射单元中形成均匀递增的正的或者负的相移。
- Figure 7-1 and subsequent diagrams show only a limited number of radiating elements. 图7-1和后面的图表只显示了少量辐射单元的情况。
- In a phase-scanned radar system, the radiating elements are fed from a radar transmitter through phase-shifting networks or "phasers. 在相扫雷达系统中，从雷达发射机馈送到发射单元要经过移相电路或称为“移相器”。
- The previous discussion addressed the theory required to compute the relative phase shift between adjacent radiating elements in order to position the beam of an array-type antenna to a specific angle off of the antenna boresight axis. 前面的讨论中给出了计算使阵列天线的波束相对天线视轴线偏移一个给定角度所需的相邻单元间相对相移的理论。
