The fusion radiating unit 1 and the intermediate frequency radiating unit 3 are radiating units with the same working frequency band and different forms; the low-frequency bowl-shaped radiating element 2 and the low-frequency cross radiating element 5 are radiating elements with the same working frequency band and different forms; in the high-frequency array, the fused radiating element 1 and the low-frequency cross radiating element 5 are added to realize the maximization of the gains of the low-frequency band and the medium-frequency band of the antenna by inserting the fused radiating element 1 and the low-frequency cross radiating element 5 in the compact high-frequency radiating element array, and meanwhile, the performance index of the high-frequency band of the antenna is not influenced.

Preferably, the die-cast radiating element sagging column 1014a or the die-cast radiating element sagging column 1014b is added to the end of the die-cast radiating element radiating arm 1011, which equivalently increases the electrical length of the intermediate frequency, reduces the dimension in the plane direction of the intermediate frequency, and reduces the influence of the overlapping of the intermediate frequency and the high frequency projection direction.

Preferably, the PCB radiating unit loading posts 1024 are selectively loaded at two positions in the horizontal direction of the PCB radiating unit 102; that is, preferably, the loading structure is provided at both ends of the fusion radiating element in the horizontal direction, and the cross polarization ratio of the radiation pattern can be optimized.
The embodiment provides the adjustable radiating unit, aiming at different application environments, branches can be selectively loaded to realize matching, and the adjustable radiating unit is simple in structure and obvious in effect. The radiation unit provided by the embodiment improves the matching characteristic of the radiation unit by adding the branch at the tail end of the vibrator arm aiming at a plurality of positions in the fusion scheme, improves the radiation characteristic of the radiation unit in the environment, reduces the die sinking period and the cost due to the optimized PCB printed circuit structure, and is flexible in design.
