Problems solved by technology

When designing a narrowband antenna, it is relatively easy to achieve a relatively stable standing wave ratio and gain effect within its operating bandwidth. However, the ultra-wideband antenna has the characteristics of an extremely wide operating frequency bandwidth, ensuring its corresponding performance parameters within the operating frequency band Difficult to meet the target requirements

Abstract

The invention relates to a ground target positioning testing device which comprises a transmitting antenna and a receiving antenna, the transmitting antenna is a broadband wide-beam antenna, the receiving antenna is a broadband narrow-beam array antenna, the working frequency of the transmitting antenna is 2.5-4 GHz, the beam width is larger than 90 degrees, and the beam angle of the receiving antenna is smaller than 10 degrees. The broadband wide-beam antenna is a planar tapered slot slit Vivaldi antenna, and the broadband narrow-beam array antenna is formed by arranging eight planar tapered slot slit Vivaldi antennas as array elements. According to the invention, the beam width of the transmitting antenna is improved, the beam width of the receiving antenna is reduced, the miniaturization requirement is met, the antenna can be used for high-power transmission and long-distance target detection, and the accuracy of target positioning is improved.

Description

technical field [0001] The invention relates to the technical field of antenna design, in particular to a ground target positioning test device. Background technique [0002] The Vivaldi antenna, also known as a tapered slot antenna (TSA), is an ideal antenna for broadband applications. It is simple in structure, easy to manufacture, and has high gain at the same time. When designing a narrowband antenna, it is relatively easy to achieve a relatively stable standing wave ratio and gain effect within its operating bandwidth. However, the ultra-wideband antenna has the characteristics of an extremely wide operating frequency bandwidth, ensuring its corresponding performance parameters within the operating frequency band Meeting the target requirements is not easy to achieve. In addition, due to the increasing requirement for the convenience of target detection testing, it is of practical value to integrate the designed antenna into a portable system to further reduce the siz...
