QW152NB

RF Antennas

Radio Frequency (RF) antennas are essential components of many communication systems. They are used to send and receive radio signals, allowing information to be transmitted between two or more locations. In addition, antennas can be used in radar applications to detect and track targets, such as vehicles, ships, and planes. RF antennas come in a variety of shapes and sizes, and are designed for a particular purpose or application. For example, a certain antenna may be designed to transmit a signal over a long distance, while another may be designed to detect a signal from a low power source. Depending on the application, antennas may be omnidirectional, directive, or a combination of the two.

The QW152NB is a type of RF Antenna designed for applications that require long-range directional transmission. The antenna is an "L" shaped directional antenna, and is made up of two dipole elements connected in parallel. The two elements are designed in a "L" shape orientation, and are do not require an antenna array for beam-forming. This makes the QW152NB ideal for applications that require a single antenna.

The QW152NB is designed for operation between 865 - 868 MHz. It offers a peak gain of 11.3 dB with a 20 degree beamwidth, and boasts an impressive maximum power input of 25W. The antenna has been designed to be used in outdoor environments, and features an IP67 rated aluminum housing. Additionally, the antenna is also UV resistant and has been tested to survive harsh environmental conditions.

The working principle behind the QW152NB is based on the concept of directive transmission. A directive antenna is an antenna designed to beam the output of its transmitter in a certain direction, providing better coverage area performance in a particular direction than an omnidirectional antenna. The QW152NB is designed to send and receive signals in an omni-directional pattern, meaning that it can transmit in all directions simultaneously. By using a pair of dipole elements in a "L" shape orientation, the QW152NB creates a directivity pattern with a wide beamwidth (20 degrees) and high gain (11.3 dB). This allows it to transmit a signal over a long distance, with a low amount of power input.

The QW152NB is ideal for applications that require long-range, directional transmission. It is well suited for applications such as point-to point communication, long range backhaul, and wireless LANs, as well as applications that require high gain coverage in a specific direction. Additionally, the antenna is also ideal for applications that require low-power transmissions, such as IoT and machine-to-machine (M2M) communication.

In conclusion, the QW152NB is a radio frequency antenna designed for applications that require long-range, directional transmission. The antenna is made up of two dipole elements connected in a "L" shape orientation, which creates a directivity pattern with a wide beamwidth and high gain. It is ideal for applications that require low-power transmissions, as well as point-to point communication, long range backhaul, and wireless LANs.
