Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] The applicable frequency bands of the ultra-wideband rectangular slot strip antenna triangular array of the invention are P and L bands. as attached figure 1 As shown, the ultra-wideband rectangular slot strip antenna triangular array of the present invention includes a strip antenna unit 1 , a positioning piece 2 , a positioning piece 2 3 , a reflector 6 and an N-type connector 7 . Thirteen strip antenna units 1 of the present invention form an inverted triangle array and are distributed on the reflector 6; four strip antenna units 1 of the first row and the third row and five strip antenna units 1 of the second row are composed of Positioning piece one 2 and positioning piece two 3 are fixed, form three rows (four five four) inverted triangular arrays like this. The positioning piece 1 2 and the positioning piece 2 3 are installed on both sid...

Abstract

The invention relates to a radar ultra-wideband antenna array, in particular to a strip antenna unit and an ultra-wideband rectangular slot strip antenna triangular array, which can be used for a large ultra-wideband antenna triangular array. The ultra-wideband rectangular slot strip antenna triangular array altogether comprises thirteen strip antenna units, and an inverted triangular array is formed and is distributed on a reflecting plate. The first row and the third row present four strip antenna units, and the second row presents five strip antenna units. Positioning pieces are mounted ontwo sides of the strip antenna unit, and while the strip antenna unit is fixed, the strip antenna unit can be ensured to be well grounded. The strip antenna unit adopts a strip antenna type formed bymultiple layers of microstrip plates, the antenna bandwidth can be effectively widened, and the antenna size is narrowed.

Description

technical field [0001] The invention relates to a radar ultra-wideband antenna array, in particular to a strip antenna unit and an ultra-wideband rectangular slot strip antenna triangular array, which can be used for a large ultra-wideband antenna triangular array. Background technique [0002] Common UWB antenna units include tapered slot line antennas, Vivaldi antennas and multi-layer laminated patch antennas. Based on these three antenna types, various antenna units have been developed. In order to further widen the antenna bandwidth, the microstrip antenna type can be transformed into a strip antenna type. [0003] Due to the influence of mutual coupling between antenna elements, the radiation efficiency of the antenna elements in the array will be greatly reduced, and a single antenna cannot simply be used to form an array. When designing the antenna array, the influence of the antenna array on the centering unit should be fully considered. Contents of the invention ...
