Abstract

The invention discloses a room division antenna. By placing two parallel dipoles respectively in the first polarization direction, the second polarization direction and the third polarization direction which are perpendicular to each other, six dipoles They are orthogonal to each other to form three-polarized antennas, realize three-way data streams, use the complex characteristics of indoor propagation directions to obtain MIMO effects, improve system capacity and spectrum utilization, and form an array of dipoles in each polarization direction in parallel to achieve The reasonable design of the processing technology can change the antenna electromagnetic field radiation direction through the corresponding amplitude and phase combination without changing the antenna structure, adapt to the needs of different indoor coverage scenarios, and occupy a small space. The indoor antenna includes: a balun structure, a feed point, six feed connection conductors, a mirror reflection ground plate, a feed network board, two parallel dipoles in the first polarization direction, and a second polarization Two parallel dipoles in the direction of polarization and two parallel dipoles in the direction of the third polarization.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a room division antenna. Background technique [0002] The existing communication antennas used in indoor distribution systems are single-polarized or dual-polarized, and single-polarized or dual-polarized indoor distribution antennas cannot meet the requirements of the third generation in terms of spectrum utilization, capacity, and antenna radiation directionality. Mobile communication technology (3rdGeneration, 3G), fourth generation mobile communication technology (4-Generation 4G) and requirements for future network and business development. [0003] The currently widely used single-polarization indoor sub-antenna combination can meet the high-capacity requirements of the system for antennas, but the single-polarization antenna array occupies a large space (with a distance of 5-10 working wavelengths), which has a great impact on the actual indoor distribution construc...
