A dipole antenna is a simple type of radio antenna that consists of two conductive elements, usually made of metal, which are oriented in opposite directions. It is commonly used for transmitting and receiving radio waves. The length of each element is typically half the wavelength of the frequency it is designed to operate on, making it efficient for various communication applications. Dipole antennas can be found in many settings, from amateur radio to commercial broadcasting. They are often easy to construct and install, making them popular among hobbyists. Their design allows for a relatively wide bandwidth, which means they can effectively transmit and receive signals across a range of frequencies.
