4000AT44A1800E Application Field and Working Principle

4000AT44A1800E is an RF antenna typically used for radio frequency. It is designed for applications with transmit power of up to 10 watts, and operate in a frequency range of 400 MHz-1800 MHz with an antenna length of 44 cm. Its application field includes GSM/GPRS/2G/3G/4G base station, WiFi system, and other small wireless communication environments. It is also applied in other commercial and industrial applications such as ITS, AVL, or navigation systems.

4000AT44A1800E Antenna Working Principle

The 4000AT44A1800E antenna works by radiating the electromagnetic wave generated by an internal source to the surrounding space. The antenna is designed with vertical dipole radiation pattern, meaning that it radiates horizontal electric field with a small partial vertical field. This radiation pattern requires an optimal distance from the ground or any other ground planes for better performance. The antenna is built with a choke balun, which helps to ensure the power is divided evenly between the two antenna elements.

The choke balun also helps improve the antenna performance because it prevents electric current from traveling in the ground plane and disturbs the antenna field in the near-field range of the antenna. The antenna feed point is located at one quarter of the circuit length, rather than in the center. This helps the antenna to receive an optimal signal and transmit the best performance.

4000AT44A1800E Benefits

The 4000AT44A1800E is an excellent choice for many applications because it offers multiple advantages. Some of these advantages include:
