Antenna core is a type of antenna element which is used to create an antenna array. It can be used to provide a variety of functions, including receiving wireless signals and transmitting them.

The core of an antenna is the backbone of the antenna, which is responsible for the radiating and receiving of signals. It usually consists of a metal rod that is surrounded by a dielectric material. This dielectric material can be plastic, rubber, or air.

When used in antenna arrays, an antenna core is connected to other antenna elements in a specific configuration to maximize the antenna's performance. Each antenna in the array is usually connected to a balun, which is a device that converts balanced signals into unbalanced signals. This helps to reduce the amount of interference caused by other antennas in the vicinity.

The core of an antenna also influences the antenna's gain. The higher the gain of an antenna, the greater its range. This is because antennas with higher gain can send out strong signals over a wider area than antennas with low gain.

Antenna core can be used for both indoor and outdoor applications. It is used in many devices, including base stations for cellular networks, WiFi routers, and satellite dishes.

To sum up, an antenna core is an essential component of an antenna array. It is responsible for transmitting and receiving signals, and is often connected to baluns to reduce interference. Moreover, its size and shape influence the antenna's gain, which determines the range of the antenna.
