Cheap drones may not be popular in agriculture or filming, but they have great potential for military applications. Its manufacturing cost, high flexibility and versatility, because the battlefield is more common to use disposable products, so cheap drones in the battlefield has a broad application space. In the complex environment of the battlefield, the most expensive military equipment will be quickly consumed, so the ultra-cheap drones and other high-end weapons have the same combat system....
Millimeter-wave radar is a special radar technology that uses very short wavelength electromagnetic waves. The radar system transmits electromagnetic wave signals that are blocked by objects in its transmission path and then reflected. By capturing the reflected signal, the radar system can determine the distance, speed and angle of the object. Millimeter-wave radar transmits signals with a wavelength of millimeters. This wavelength is considered short in the electromagnetic spectrum and is one...

Why are the demands for Drone Jammer becoming more and more diverse? Today, drones have flown into more and more fields, from military reconnaissance to commercial photography, from farm work to express delivery, they are everywhere. But with the popularity of drones, some questions have gradually emerged: How to ensure the safety of drone flights? How to protect privacy from being invaded? At this time, the UAV interference module becomes particularly important. Why do people need Drone Jammer...
With the rapid development of science and technology, drones have been increasingly integrated into our daily lives. Whether it is aerial photography of beautiful scenery, farm work or emergency rescue, drones play an irreplaceable role. However, every time has two sides, and the popularity of drones has also brought about some problems, the most prominent of which is the impact of the jammer signal blocker. (signal jammer) As the name suggests, it is a device used to interfere with the normal...
"Eyes in the sky, protect safety" Nowadays, science and technology are becoming more and more developed, and people's living standards are getting higher and higher. Material needs have gradually changed from material needs to spiritual needs, and more needs are met in the spiritual world. Therefore, drones are widely used by humans for photography, etc. However, with the popularity of drones, more and more security issues and privacy issues have become prominent.

Almost all UAVs currently have the same structure, using fan-blade propellers. This kind of drone has a fatal shortcoming that if the fan blade touches other objects, it may be damaged or crashed instantly. A student from RCA, Marcus Kung, made an innovative design for this pain point and developed a fanless drone model. In fact, the principle of this innovative UAV is very simple. It uses four turbofans to push the air at high speeds to form thrust. The principle is similar to that of a jet...

1 antenna 1.1 The role and position of the antenna The power of the radio frequency signal output by the radio transmitter is transmitted to the antenna through the feeder (cable), and the antenna radiates it in the form of electromagnetic waves. After the electromagnetic wave arrives at the receiving location, it is followed by the antenna (receiving only a very small part of the power) and sent to the radio receiver through the feeder. It can be seen that the antenna is an important radio...
Antenna polarization The polarization of radio waves refers to the relationship between the direction of the electric field and the direction of propagation. It represents the orientation of the electric field vector in the direction of maximum radiation. In practice, due to the different placement of the transmitting antennas, the electric field has only vertical or parallel components to the ground. The former is called a vertically polarized wave. Our broadcast transmitting antenna is...
In many cases, in order to reduce the space occupied by the antenna, we often need to reduce the size of the antenna. So how can the antenna still accurately resonate when the antenna size is reduced? This is the issue we discuss below. An antenna shorter than a quarter wavelength multiple is capacitive. This is because it does not generate resonance and its combined phase relationship between current and voltage is very similar to that of a capacitive circuit. Then, we can add an inductor to...
The basic principle of the antenna's emission is that electricity propagates in the conductor at a speed close to light. When it encounters a discontinuity in the conductor, it will be reflected back to the signal source. If the current is alternating, and the reflected current returns to the origin or feed point at the appropriate time, the current will be strengthened by subsequent cycles, so that only a small amount of energy is required to maintain the standing wave in the antenna. That...
