Abstract

The invention discloses a dipole antenna with single zero point compensation. The dipole antenna comprises a dielectric substrate, and a dipole antenna and a microstrip yagi antenna which are arrangedon the dielectric substrate. According to the dipole antenna, dipole arms are arranged on the front surface and the back surface of the dielectric substrate; the dipole arms on the front surface andthe back surface of the dielectric substrate are connected; the dipole arm on the front surface of the dielectric substrate and the dipole arm on the back surface of the dielectric substrate adopt a double-array symmetrical structure; the dipole antenna can perform omnidirectional radiation on an H surface, and a feed port is led out of the dipole antenna; and the microstrip yagi antenna is used for compensating a radiation zero point of the E surface of the dipole antenna in a strong directivity manner in the direction of a director of the microstrip yagi antenna. The dipole antenna with single zero point compensation can achieve the purposes that the antenna is suspended above the space, and the radiation range covers the periphery and the lower portion of the whole space.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a dipole antenna with single zero point compensation. Background technique [0002] Omnidirectional antennas have been widely used in the field of mobile communications. With the rapid development of electronic technology and communication industry, the requirements for omnidirectional antennas are getting higher and higher. As an omnidirectional radiation antenna, printed dipole antennas have become an antenna An important research direction of the subject. In recent years, top-mounted omnidirectional radiation antennas have been widely used in indoor distributed antenna systems, but traditional top-mounted omnidirectional radiation antennas usually use monopole antennas, and top-mounted omnidirectional radiation antennas based on dipole antennas are not Not studied in depth. Compared with monopole antennas, dipole antennas do not need to be installed on a larger ground plane...
