Abstract

The disclosed antenna assembly is composed of N pieces (N is larger than or equal to 1) of antenna unit and M pieces (M is larger than or equal to 1) of ground of antenna. K pieces (K larger than zero and smaller than N) of antenna unit are positioned on the ground of antenna between main body and case of wireless communication terminal. Other (N-K) pieces of antenna unit are positioned on the ground of antenna between back of screen of turnable cover and case of wireless communication terminal. Through feeder apparatus, N pieces of antenna unit are connected to relevant transmitter or receiver. Features are: low spatial correlation, no radiation injury, low cost and easy of manufacturing. The invention can be widely applied for wireless communication for obtaining space diversity, angle diversity or polarization diversity of radio wave propagation, or in use for transmitting or receiving time-space coding or multiple inputs and outputs wireless communication system.

Description

technical field [0001] The invention belongs to the technical field of wireless communication diversity antennas, in particular to the wireless communication terminal diversity antenna technology. Background technique [0002] With the rapid development of wireless communication, the number of users is increasing day by day, and the data service is growing continuously. The wireless communication system of single-antenna transceiver is facing severe capacity bottleneck test. It is necessary to further improve the capacity and quality of the current wireless communication system, and seek new Technical solutions. Multiple transmission and multiple reception (MIMO) technology is a new wireless communication technology that utilizes multiple transmitting and multiple receiving antennas. Its transmitted data stream is separated into multiple sub-data streams, which are transmitted simultaneously at the same frequency through different antennas after modulation. Through the scat...
