CAF94136

RF Antennas

A CAF94136 is an antenna designed for radio frequency (RF) applications. It is a dipole antenna typically installed in a variety of communication systems, such as mobile phones, Wi-Fi access points, satellite receiver systems, radio navigation systems, and two-way radios. This type of antenna is often used to provide a wide coverage area and a longer transmission distance. In addition, it is designed to be omnidirectional and can easily be configured for directional operations.

Application Field

The CAF94136 is a low-profile antenna designed to transmit radio waves over long distances. This type of antenna is commonly used in mobile phone systems, such as cellular base stations which utilize frequency reuse techniques to provide wide coverage areas. It is also commonly used in Wi-Fi applications where the antenna is used to provide a reliable connection to the internet. Additionally, it is often used in satellite receiver systems to provide greater signal reception.

Other applications include radio navigation systems such as Global Positioning Systems (GPS) and two-way radio systems. Finally, the CAF94136 is sometimes used in military applications where the antenna is used to transmit and receive radio frequency signals over long distances.

Working Principle

The CAF94136 operates on the principle of electromagnetic radiation. The antenna is designed to radiate radio waves in a particular frequency range, such as the 800-1000MHz range or the 2.4 GHz Wi-Fi frequency range. The antenna is composed of a dipole antenna array which works to convert electrical signals into electromagnetic waves.

The dipole antenna consists of two conductive rods which extend out from the antenna and are separated at a certain distance. The distance between the two rods is known as the dipole antenna’s resonant length. This distance is specific to the frequency which the antenna is designed for. When an electrical signal is applied to the antenna, the resonance of the antenna excites the electromagnetic waves, which are then radiated in the form of radio waves.

As these radio waves propagate, they interact with the surrounding environment, such as walls, buildings, and other objects, which can then reflect or absorb some of the energy, reducing the total signal strength. This is why antennas need to be placed in an open area with minimal objects which can interfere with the signal.
