[0001] MULTIPATH MITIGATING SHIELD

[0002] Field of the Invention

[0003] The present invention relates to a shield that can be integrated into unmanned aerial vehicles, allowing them to diminish the effect of multipath signals reaching their antenna.

[0004] The most important technical distinguishing feature of the invention, which is a multipath mitigating shield, is its body. It is light as a result of its plastic body. Due to its light weight, it can be integrated into UAVs (unmanned aerial vehicles) by increasing its portability, allowing multipath mitigation to be performed in the air without disturbing the flight ergonomics and flight stability of unmanned aerial vehicles.

[0005] Prior Art

[0006] Today, a choke ring antenna usually refers to a type of antenna configuration. This design is placed around the antenna to reduce the effects of multipath phenomena, especially in GPS (Global Positioning System) receivers and other RF (Radio Frequency) applications, it is a structure designed to mitigate or block incoming signals from a specific direction.

[0007] The choke ring shield consists of conductive elements arranged in ring sets, usually with a circular structure. This design preventsmultipath signals from reaching the top of the antenna, allowing high angle signals from satellites to be received. This is particularly effective when used in highly reflective environments to improve the accuracy of GPS receivers. The Chinese patent document numbered CN 217215079, which is relevant to the subject matter in the art, mentions a choke ring antenna structure. The document describes a technical difference in the way the body and the body are mounted together.

[0008] Since the choke ring shield typically has a metal structure, it can pose some challenges for its use, especially on lightweight carrier platforms such as unmanned aerial vehicles (UAVs). The weight of metal structures can negatively affect the flight performance of unmanned aerial vehicles and increase energy consumption. Also, metal structures can often create practical problems in terms of portability and integration.

[0009] As mentioned above, there is no mention of a shield that does not have a metal structure or uses lightweight materials (materials such as plastic or carbon fiber), thereby reducing the weight of the shield and providing a more suitable flight structure for unmanned aerial vehicles, GNSS antennas, effective damping of signals caused by multi-reflections.
