A loop antenna is an antenna designed to receive radio signals more efficiently than other antennas. Loop antennas are considered more efficient than other antennas because they are mobile, operate over a wide frequency range, and consume less power. The performance of an loop antenna depends entirely on its construction and layout, although other factors may also play a role. Loop antennas locate areas with ideal signal strength and improve signal quality and communication.
Structure
The loop antenna is generally composed of a peripheral deployment truss and a cable network system, which refers to a spaceborne antenna where the deployment truss structure is located on the periphery, and the center and radial direction are all composed of cable network systems. The circumferential trusses around the loop antenna are generally polygonal structures, which are periodically repeated to form a closed "ring" structure.
Principle
Loop antennas are made of copper rings or other conductive metals connected to the same capacitor at both ends. When the user adjusts the capacitance of the loop antenna, the frequency is adjusted in reverse. Therefore, if the user increases the capacitance of the loop, the frequency increases. On the other hand, if the user reduces the capacitance of the loop, the frequency decreases. This is because the capacitor of the loop holds the current and releases it after a specified time. This means that the longer the capacitor holds the charge, the more radio waves from the antenna spread, and the lower the frequency. Lower frequencies will not travel as far, but the signal will be stronger.
Merit
Loop aerials have several important advantages that others do not. For example, loop antennas broadcast and receive various radio frequencies. They are also portable and small enough to be integrated into many wireless devices without requiring the user to see it. Loop antennas are also very affordable, ergonomic and are the most common type of antenna used for home use.
Application
A loop antenna determines the direction in which the frequency comes from and how strong the radio signal is in any given area. They also reduce or eliminate interference from other electromagnetic waves by receiving only signals with specific frequencies. Loop antennas exist in many different types of radios and can operate in conjunction with the radio itself.

A:Yes, we are the manufacturer. Our company has 15 years of professional experience in the field of telecommunications and can design and manufacture various microwave waveguide components, coaxial components, antennas and other telecommunications components for the global market.
2. Q: How do I place an OEM order?
A: 1. We will manufacture these products according to the mechanical drawings you provide. Some minor changes may occur during the production process to ensure that we can meet your electrical specifications. Or we can take the first set as a sample to see if it meets your specifications. After communication, the buyer and seller reached an agreement on product details, packaging, purchase quantity, unit price, delivery time, payment terms, etc.
2. The buyer sends a formal PO (Purchase Order) or the seller sends a formal PI (proforma invoice) with detailed terms and conditions.
3. Q: How to solve the after-sales service problem?
After receiving the goods, if you have any dissatisfaction or other problems, please contact us as soon as possible, we will give you a quick response and reasonable solution.
4. Q: How long is your delivery time?
