Abstract

The invention discloses an indoor multiple input multiple output (MIMO) antenna which comprises an antenna cover, a radiator and a reflecting plate. The radiator is arranged on the reflecting plate, the antenna cover is arranged above the radiator and surrounds the radiator, the radiator comprises a metal patch and two half-wavelength dipoles, the half-wavelength dipoles are respectively printed on two printed circuit boards (PCBs) which are placed in mutual orthogonal cross mode, and the metal patch and the PCBs placed in orthogonal cross mode are evenly distributed on a longitudinal central line of the reflecting plate. The MIMO antenna can replace a wall-mounted antenna in an existing network directly, can support a double-channel device of time division-synchronization code division multiple access (TD-SCDMA), wireless local area network (WLAN) and long term evolution (LTE) frequency band, saves a large amount of resources for smooth transition of an indoor coverage system, and simultaneously provides more selection schemes for a future network integration scheme. The MIMO antenna is simple in structure, easy to assemble and debug, low in cost and favorable for mass production.

Description

technical field [0001] The invention relates to a mobile communication antenna, in particular to a MIMO antenna of a mobile communication indoor distribution system. Background technique [0002] With the rapid development of wireless communication technology, mobile users have higher and higher requirements for the capacity and quality of wireless communication. However, the current wireless channels have problems such as multipath attenuation, spectrum congestion, and noise interference, which greatly affect the data rate. improve. [0003] Multiple-input multiple-output ( MIMO ) antenna technology can double the quality and data rate of wireless communication without increasing the bandwidth and transmission power, especially the indoor stable and rich multi-path wireless environment is very conducive to the use of MIMO multiple Antenna technology. [0004] A broadband antenna that can satisfy multiple networks at the same time will undoubtedly meet the needs of operato...
