RF antennas have been employed in many electronic applications, with different frequency for working range and different type for different working environment. One of the antennas widely used in radio frequency or wireless communication is the BB3805CN.

It is a kind of pigtail RF antenna. It is a rectangle-shaped antenna with DC power applied through an SMA connector on it. Its operating frequency range is from 2.4 to 5.8 GHz , making it suitable for the popular wireless standards , such as Wireless Fidelity (Wi-Fi) and Bluetooth. The antenna has a wide range of applications. It can be used in wireless communication applications , such as Bluetooth short-range communication, Zigbee, Z-Wave, Wi-Fi, and other applications that require short-range communication.

The working principle of the BB3805CN is quite simple. The antenna is basically a half-wave dipole antenna with two metal strips. These two metal strips act as the radiating elements of the antenna. When an AC current is applied to the antenna, the electric and magnetic fields interact with each other to produce an antenna radiation pattern. The radiation pattern depends on the size of the antenna and its orientation relative to the ground plane. When the antenna is connected to a radio frequency source, the antenna radiates a beam that is directed away from the source.

The BB3805CN also features a built-in impedance matching circuit, which helps to ensure that the antenna is matched with the antenna connector. This helps to reduce any signal losses that might occur. Additionally, the antenna includes a shielding cover, which helps to protect it from external interference.

In summary, the BB3805CN is a pigtail RF antenna with a wide range of applications in radio frequency or wireless communication. It has a wide frequency range and a built-in impedance matching circuit, as well as a shielding cover for protection against external interference. This makes it ideal for applications such as Wi-Fi, Bluetooth, and other short-range communication applications.
