Several high frequency radiating elements, low frequency radiating element on face, the height of high frequency radiating element will be less than low frequency radiating element
Highly,
High frequency radiating element is nested in low frequency radiating element or is arranged between two neighboring low frequency radiating element, or
A part of high frequency radiating element is arranged in low frequency radiating element, and another part high frequency radiating element is placed on adjacent
Between two low frequency radiating elements.
A kind of ultra-wideband dual-band and dual-polarization plate antenna that the utility model is provided, including reflecting plate 10, it is arranged on reflection
The positive high frequency radiating element of plate 10, low frequency radiating element, metal frame, U-shaped isolation and the feedback for being arranged on the back side of reflecting plate 10
Electric network.
Reflecting plate 10 is an aluminum metal plate.Radiating element is connected with feeding network, for providing in parallel to radiating element
Feed.
In the utility model, radiating element includes high frequency radiating element 30 and low frequency radiating element 20.Low frequency radiating element
20 using the dual polarization low-frequency vibrator for being die casting, and it is 790MHz-960MHz that it, which covers frequency range,.
What high frequency radiating element 30 was used is also the dual polarization vibrator of die casting, and it is 1710MHz-2700MHz that it, which covers frequency range,.
In this example, high frequency radiating element 30 and low frequency radiating element 20 are using nested and assembled by the way of being separated by, and high frequency spoke
The height of low frequency radiating element 20, the dress coaxial with low frequency radiating element 20 of high frequency radiating element 30 will be less than by penetrating the height of unit 30
Fit on reflecting plate 10, and overlapped with the axis of reflecting plate 10.In this example, the multiple composition of high frequency radiating element 30 high frequency antennas
Array, multiple low frequency radiating elements 20 constitute low frequency antenna array, while low-and high-frequency array is on the same axis, so just form
