Explore: Parasitic Elements (antennas)

number of other elements which are not driven, called parasitic elements. The driven element is often a dipole. The parasitic elements act as resonators

An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves

in an end-fire array; these elements are most often metal rods (or discs) acting as half-wave dipoles. Yagi–Uda antennas consist of a single driven element

three-element Yagi–Uda antennas connected together, each set tuned to a different frequency. LPDA antennas look somewhat similar to Yagi antennas, in that they

or "beam" antennas). An antenna may include components not connected to the transmitter, parabolic reflectors, horns, or parasitic elements, which serve

telecommunications and radar, a reflective array antenna is a class of directive antennas in which multiple driven elements are mounted in front of a flat surface

antennas are fed in phase. Doing so with horizontal dipole antennas retains those dipoles' directionality and null in the direction of their elements

summaries of multiple different types of antennas used for radio receiving or transmitting systems. Antennas are typically grouped into categories based

quad elements produces diminishing returns: "Whereas parasitic beams having twenty or thirty parasitic directors are efficient, high gain antennas, it

balanced load. Loop antennas can be divided into three categories: Large loop antennas: Also called self-resonant loop antennas or full-wave loops; they
