这项工作描述了商业上可用的封装射频微机电系统（RF MEMS）开关与辐射方向图可重构微带天线的集成。RF MEMS开关的大多数应用仅将开关视为电路元件。相比之下，在这个特定的天线封装开关的实现必须解决不仅是简单的开关的打开/关闭的行为，但也对可重构天线的辐射特性的影响。在这里，两个Radant MEMS单刀单掷（SPST）SPST-RMSW 100（封装RF MEMS）开关用于重新配置端射和宽边之间的谐振方形螺旋微带天线的辐射模式在一个共同的阻抗带宽。交换机插入，匹配网络设计，和其他问题的解决。模拟和测量天线的结果，以及在这方面的未来工作的建议，提供。
This work describes the integration of commercially available packaged radio frequency microelectromechanical system (RF MEMS) switches with radiation pattern reconfigurable microstrip antennas. Most applications of RF MEMS switches consider the switches as only circuit elements. In contrast, the implementation of packaged switches in this particular antenna must address not only the simple open/closed behavior of the switches but also their impact on the radiation characteristics of the reconfigurable antenna. Here, two Radant MEMS single-pole single throw (SPST) SPST-RMSW100 (packaged RF MEMS) switches are used to reconfigure the radiation patterns of a resonant square spiral microstrip antenna between endfire and broadside over a common impedance bandwidth. Switch insertion, matching network design, and other issues are addressed. Results for both simulated and measured antennas, as well as recommendations for future work in this area, are provided.
