A dipole antenna is a type of radio antenna that is made up of two conductive elements, typically metal rods or wires, that are oriented in opposite directions and connected to a radio transmitter or receiver. The two elements are usually of equal length and arranged in a straight line. It is commonly used in radio communication and broadcasting because it has a wide frequency range and can transmit and receive signals from various directions. Dipole antennas are widely used in everyday applications like home Wi-Fi networks and television broadcasting.
