MULTI BAND DUAL POLARIZATION ANTENNA

摘要

A multi band dual polarization antenna is provided to reduce interference between a first radiation element and a second radiation element by arranging the second radiation element between the first radiation elements. A multi band dual polarization antenna includes first radiation elements(304A,304B) for a radiation pattern of a first frequency band and a second radiation element(306) for the radiation pattern of a second frequency band. The second radiation element is arranged between the first radiation elements. The first radiation element generates the radiation pattern by the combination method. The second radiation element generates the radiation pattern by the vector composition method. The first radiation element is comprised of four first dipole elements. The second radiation element is comprised of four second dipole elements. When the first dipole elements are arranged in - 45 to + 45 degrees, the second dipole elements are arranged in a vertical direction and a horizontal direction.
