RF Antennas: WLA.01 Application Field and Working Principle

The WLA.01 is a type of RF antennas designed to receive and transmit electro-magnetic waves in the radio frequency band. The antenna is mainly used in Wireless communication, radio astronomy, remote sensing, mobile phone base stations and radar systems. This type of antenna has a wide range of applications due to its high gain, wide bandwidth, high directivity, low VSWR and other advantages.

Most WLA.01 antennas are linear arrays, which consist of a number of antenna elements that are arranged in a straight line and connected together. Each element is usually a dipole antenna or other radiators with common electrical characteristics. The array elements are spaced and configured to achieve a desired radiation pattern, which mostly depends on the overall length of the array and the spacing among each element. In some cases, the antenna array is also designed to have a self-focusing effect, which allows the signals to be transmitted in a particular direction with high directivity.

The working principle of WLA.01 antenna is based on the theory of radiation from current element. To make the antenna directional, it usually requires some form of array synthesis. Since each array element has the same phase and amplitude relationships, the output of the array is a function of the chosen phase and amplitude shift. This is achieved by using a combination of phasing and amplitude feeding networks, where each antenna element receives a signal with different phase and amplitude based on its location.

The antenna’s gain and directivity are closely related to the overall length of the array, the spacing between elements and the configuration of radiators. The type of array determines the antenna’s radiation pattern, which is mainly used to control the radiation energy. In addition, the antenna’s effective distance of transmission can be improved by increasing the antenna’s gain and directivity.

The WLA.01 antenna is a versatile antenna, which can be used for various applications. It is generally used for receiving and transmitting signals in the radio frequency band, such as for wireless communication, radio astronomy, remote sensing and mobile phone base stations. It is also suitable for radar systems as it has excellent gain, directivity, and low VSWR.

In summary, the WLA.01 is an efficient and versatile antenna which is used in a wide range of applications, such as wireless communication, radio astronomy, remote sensing, mobile phone base stations and radar systems. Its main advantages include a high gain, wide bandwidth, high directivity, and low VSWR. Its working principle is based on the radiation from current elements, and requires a combination of phasing and amplitude feeding networks to achieve a desired radiation pattern.
