This article will discuss the application field and working principle of the YF880012-61NF antenna.

Application Field

The YF880012-61NF antenna is a medium-size antenna that is suitable for use in applications requiring longer range and wider coverage. The antenna provides a wide range of radio frequency (RF) coverage from 260MHz to 4.9GHz, making it suitable for various applications, such as short- and long-range communication, including Wi-Fi, Bluetooth, and digital radio broadcast.

The YF880012-61NF antenna is also designed to be used indoors and out, making it ideal for home and industrial usage. The omnidirectional pattern and the shielding structure make the antenna ideal for outdoor usage. The antenna also has high gain and good directivity, making it suitable for outdoor applications requiring high-power transmissions. The antenna is also compact in size, making it easy to install and transport.

Working Principle

The YF880012-61NF antenna works by transmitting and receiving signals. When transmitting, the antenna sends out a strong electromagnetic field in an omnidirectional pattern, which then propagates in all directions. When receiving, the antenna captures the radio waves coming from the source, amplifies them, and then transmits them to the receiver.

The antenna’s main components are the parasitic element, the dielectric substrate, the ground plane, and the radome. The parasitic element is an electrically conductive element that helps in conducting the RF energy from the antenna. The dielectric substrate is composed of insulating materials that help in controlling the RF waves propagation. The ground plane provides the connection between the parasitic elements and the dielectric substrate. Finally, the radome or radome cover protects the antenna against environmental elements such as dirt and moisture.

Conclusion

In conclusion, the YF880012-61NF antenna is a medium-size antenna designed for use in telecommunication applications, such as Wi-Fi, Bluetooth, and digital radio broadcast. The antenna offers good omni-directional performance with high gain and good directivity, making it suitable for indoor and outdoor usage. The antenna works by transmitting and receiving signals between the source and the receiver, and its main components include the parasitic element, the dielectric substrate, the ground plane, and the radome.
