Abstract

The invention is based on a wideband electromagnetic dipole antenna based on an artificial magnetic conductor. The wideband electromagnetic dipole antenna comprises an electromagnetic dipole antenna and an artificial magnetic conductor (AMC) mounted together. The electric dipole of the electromagnetic dipole antenna is an electric dipole in an open fishtail shape and printed on an electric dipoledielectric plate. Magnetic dipoles are printed on two parallel magnetic dipole dielectric plates and have upper sides perpendicularly connected to the two arms of the electric dipole. A feed balun isprinted on a feed dielectric plate in parallel to the magnetic dipole dielectric plates and placed between the two magnetic dipole dielectric plates. The AMC consists of an AMC dielectric plate, and aperiodic circular metal patch and a grounding metal layer printed thereon, is parallel to the electric dipole, and is placed under the magnetic dipole dielectric plates. The AMC is equivalent to a perfect magnetic conductor (PMC), replaces the PEC reflector of a conventional antenna, and uses coaxial feed. The wideband electromagnetic dipole antenna based on the AMC is increased in the front-to-back ratio, has a stable directional diagram, and has a wide bandwidth, high gain and easy integration.

Description

technical field [0001] The invention relates to the field of electronic technology, and in particular relates to a broadband electromagnetic dipole antenna based on an artificial magnetic conductor. Background technique [0002] With the development of new mobile communication technologies, the requirements for base station antennas are becoming more and more stringent. Base station antennas are gradually developing in the direction of high gain, multi-band, wide bandwidth, multi-polarization, and reconfigurable. Traditional base station antennas have narrow frequency bands, low gain, and high profiles, which cause many inconveniences in actual use. [0003] At present, the most commonly used base station antenna structure is the dipole antenna. The dipole antenna is a very classic structure in the antenna family and is very common in daily life. Standard dipole antennas have stable omnidirectional radiation characteristics, making them a good choice for base station anten...
