4TR antenna

The invention relates to a 4TR antenna. The 4TR antenna is characterized in that the antenna comprises a reference surface and an oscillator array; the oscillator array is arranged above the reference surface, a phase center is arranged on the reference surface, and the axis perpendicular to the reference surface and penetrating through the phase center of the reference surface is L1; the oscillator array comprises four symmetrical oscillators which are arranged around an axis L1 in an array mode, and the included angle alpha formed by the axis of an oscillator arm of each symmetrical oscillator and the datum plane ranges from 30 degrees to 60 degrees. The antenna has the characteristics of simple structure, reasonable design, small size, light weight, small occupied area and the like. 本发明涉及一种4TR天线，其特点在于包括基准面和振子阵列；所述振子阵列设置在基准面的上方，在基准面上设有一相位中心，垂直于基准面且穿过基准面的相位中心的轴线为L1；所述振子阵列包括4个环绕轴线L1阵列布设的对称振子，各对称振子的振子臂的轴线与基准面所形成的夹角α均在30°～60°的范围内。本发明具有结构简单、设计合理、体积小、重量轻及占地小等特点。
