Abstract

The invention discloses a small-sized highly-insulated broadband dual-polarization printed dipole antenna, which belongs to a dipole antenna and comprises a reflecting plate, a first antenna medium plate, a second antenna medium plate and a third antenna medium plate, wherein the second antenna medium plate and the third antenna medium plate are fixed crosswise; the second antenna medium plate and the third antenna medium plate are arranged on the reflecting plate; the first antenna medium plate is fixed above the second antenna medium plate and the third antenna medium plate through positioning holes; the first antenna medium plate is parallel to the reflecting plate, and is fixed by at least three support columns; and the first antenna medium plate and the reflecting plate are arranged on the upper end faces and the lower end faces of the second antenna medium plate and the third antenna medium plate respectively. The largest innovation of the small-sized highly-insulated broadband dual-polarization printed dipole antenna is that a triangular dipole sub-arm is combined with a rectangular dipole sub-arm, so that the small-sized printed dipole sub-antenna is realized; and meanwhile, excellent performances such as broadband, high insulation degree, low cross polarization and the like are realized.

Description

technical field [0001] The invention relates to a dipole antenna, and more specifically, the invention mainly relates to a miniaturized high-isolation wide-band dual-polarization printed dipole antenna. Background technique [0002] In the past ten years, the 3G system has become increasingly mature and widely used in our country. The research on the IMT-Advanced communication system for the next generation of mobile communication has become the top priority at this stage. On January 18, 2012, at the plenary meeting of the 2012 Radiocommunication Plenum held in Geneva, the International Telecommunication Union officially considered and approved the establishment of LTE-Advanced and Wireless MAN-Advanced (802.16m) technical specifications as IMT-Advanced (commonly known as "4G ”) International standards, TD-LTE-Advanced and FDD-LTE-Advance, which were formulated by China, are paralleled to become 4G international standards at the same time. As a high-tech communication indus...
