您要查找的是不是：
- antenna element directivity 天线元方向性
- JIANGJIA JPA series is a miniature antenna element for Global Positioning Systems(GPS). JPA系列是用于全球定位系统（GPS）的小型天线元件。
- Each patch antenna element is excited by two slots on the ground plane placed perpendicularly. 阵列天线中的微带天线皆由位于接地面上的两正交槽孔所激发。
- A DBF array consists of antenna elements,N receiving modules,A/D convertors,a digital beamformer and controller. 数字波束形成(DBF)阵列由天线阵元、N 路接收组件、A/D 变换器、数字波束形成器及控制器组成。
- The transmitting array of eight Yagi-uda antenna elements with small size is proposed. 研制了以八木天线为单元的八元发射天线阵。
- DBF array consists of antenna elements,N receiving modules,A/D convertors,a digital beamformer and controller. 数字波束形成(DBF)阵列由天线阵元、N路接收组件、A/D变换器、数字波束形成器及控制器组成。
- Certain configurations, such as TV rabbit ears, also allow consumers to rotate or pitch antenna elements to reduce interference. 某些配置（例如电视机的兔耳天线）也能让用户旋转天线元件或改变仰角，以减低电波干扰。
- The space of ULA is always less than or equal to half wavelength of the transmit signal.Thus the number of antenna elements limits the aperture. 由于均匀阵的阵元间距一般取半波长，所以当阵元数目确定后天线的孔径也就随之被限定了。
