Embodiment 1
[0024] A new wide-band dual-polarized array antenna unit, including upper and lower floors 1, metalized through holes 2, radiation patches 3, reflective patches 4, central grounding through holes 5, stripline transfer structures 6, and middle floors 7 , SMD feed probe 8;
[0025] The metallized through holes 2 are located between the upper and lower floors 1 and are connected to the upper and lower floors 1. A plurality of metallized through holes 2 are distributed in a circular shape to form a cylindrical area; the radiation patch 3, the reflective patch 4, and the center ground Both the through hole 5 and the stripline transfer structure 6 are located in the cylindrical area;
[0026] The radiation patch 3 is located on the same plane as the first surface of the upper and lower floors 1, and the reflective patch 4, the middle floor 7, and the stripline transition structure 6 are sequentially away from the first surfaces of the upper and lower floors 1;
[0027] The central ...
Embodiment 2
[0032] A new wide-band dual-polarization array antenna unit, the overall technical scheme is as follows: the upper and lower floors 1, metallized through holes 2, radiation patch 3, reflective patch 4, central grounding through hole 5, stripline transfer structure 6. The middle floor is composed of 7 and patch feeding probes 8. The antenna unit is processed based on PCB technology, and the engineering implementation is simple. The upper and lower floors and the metalized through holes together form an electromagnetic shielding structure, which improves the array scanning characteristics without increasing the unit volume, and is suitable for large-angle scanning array antennas with densely arranged units. Combining the radiation and reflection double-layer patch structure increases the bandwidth of the antenna unit and realizes the equalization of the dual polarization pattern of the antenna unit. A grounding hole is added in the middle of the radiation patch of the antenna u...
