WRL-13982 application field and working principle

WRL-13982 is one of the most common antennas employed in Radio Frequency Identity (RFID) and other radio waves detection applications. It takes advantage of an antenna array structure to achieve the functionality of multiple antennas while occupying minimal physical space. This makes it particularly useful for applications that require the detection of different kinds of RF signals in a small area.

An antenna array is composed of multiple individual antennas, each radiating electromagnetic waves in a particular direction. For WRL-13982, the antenna array structure consists of four radiating slots in a four-element linear array. The array structure is designed to spread the electromagnetic field in a 360-degree polar plot, enabling the detection of radio waves from all directions. The individual antennas are designed with a directional scale to ensure that the electromagnetic field can be focused on a specific direction depending on the tuning and calibration. This further enables the antenna to be used for tracking, positioning, and distance measurement applications.

In terms of its working principle, the WRL-13982 antenna emits and receives a radio frequency signal. The signal is then directed toward the antenna array, consisting of two parts: a receive element and a transmit element. When the signal reaches the receiving element, it is then amplified and sent to the next stage where the signal is analyzed to detect the presence, strength, and location of the receiving signal. Once the signal has been detected, it is sent back through the transmission element and further amplified.

The WRL-13982 antenna’s application field is mainly in the RFID and other radio wave detection sectors. It is especially useful in applications where multiple signals need to be detected in a small area. Its compact design and 360-degree coverage make it an ideal choice for tracking and position measurement applications such as real-time location and asset tracking.

In conclusion, the WRL-13982 antenna is a highly effective antenna array with multiple applications in the RFID and other radio wave detection fields. Its array structure enables it to detect radio waves from all directions, and its compact design and directional scale makes it suitable for tracking, positioning, and distance measurement applications.
