Research on a Universal Broadband Metal Phased Array Antenna Element

利用宽带板状巴伦结构设计了一种宽带金属的对称振子相控阵单元天线,天线和馈电一体化加工,结构紧凑牢靠,通过改变地板到到金属振子的距离可方便的改变天线单元的波束宽度,以适应不同平台相控阵对扫描角的需要,通用化程度较高,设计的相控阵单元具有宽带宽角高增益的特点,可满足相控阵通用平台的需要。

A broadband metal symmetrical dipole phased array element with broadband plate-like balun structure is designed. Antenna with such elements has compact and reliable structure because its antenna and feedline are integrated. Beam width of the proposed antenna element can be adjusted easily by changing the distance between earth plate and metal dipole so that different scanning angle requirements imposed by different platforms can be satisfied. The proposed phased array element features broadband, wide angle, high gain and high universality. Therefore, it can meet the requirements of universal phased array platforms.
