[0002] As consumer-grade drones are low-cost, easy to obtain and simple to operate, with many drone manufacturers entering the market, commercial drones are rapidly penetrating into the civilian field. The number of users is gradually increasing, making supervision difficult and easy for criminals to exploit, which brings great pressure to security and confidentiality work. In response to the phenomenon of illegal drone flights, drone jammers have come into being.

[0003] After searching, a portable UAV anti-shield disclosed in publication number CN215810472U includes a square shell and a power module, a radio frequency module and an antenna module located in the shell. The power module is used to power the radio frequency module and the antenna module. The radio frequency module generates an interference signal according to the signal frequency band provided by the detection equipment and sends it through the antenna module. A handle and a counter switch for controlling the opening and closing of the antenna module are provided on the front side of the shell. The radio frequency module uses 5-way signal output to block the UAV link, which effectively suppresses most illegal UAVs on the market and is easy to carry.

[0004] However, when using the existing anti-shield, people can only manually lift the anti-shield to use it against the drone, and the anti-shield is usually heavy. When countering the drone, people need to hold it up all the time, which brings a heavy burden to the counter-work. Therefore, we propose a handheld drone anti-shield to solve the above problem.
