Abstract

The present invention relates to a multi-frequency and multi-beam MIMO antenna, pertaining to the technical field of antenna. The antenna comprises a plurality of reflecting plates (1) and a plurality of MIMO units (2). The reflecting plates (1) are successively connected with each other end-to-end around the vertical axis along the circumferential direction, the reflecting plates (1) all lean towards the direction far away from the vertical axis, and the outside of every reflecting plate is fixedly provided with one MIMO unit parallelly. Every MIMO unit comprises a plurality of dipole array elements (9), and the dipole array elements (9) are successively arranged around the axis of the MIMO unit along the circumferential direction. According to the multi-frequency and multi-beam MIMO antenna applied in WLAN / WiMAX wireless communication, beams generated by four MIMO units turn towards different directions, reflecting that the device has the characteristic of diversity of the directional diagram, indicating that the device can generate four directional beams, and meeting the energy demand of different directions. The antenna has the advantages of antenna miniaturization, low space occupation and easiness for installation.

Description

technical field [0001] The invention relates to a multi-frequency and multi-beam MIMO antenna, belonging to the technical field of antennas. Background technique [0002] Nowadays, wireless communication technology is developing rapidly, and the requirements for wireless communication speed and communication quality are increasing day by day. Multi-beam technology can realize beam isolation, frequency reuse, and improve communication capacity; MIMO technology uses multiple antennas to transmit and receive signals, which can increase data transmission rate and communication quality. WLAN / WiMAX wireless communication generally hopes to cover frequency bands of 2.4GHz-2.48GHz, 3.4GHz-3.7GHz, and 5.15GHz-5.85GHz, and requires high gain. The structure of the MIMO antenna in the prior art is complicated, the volume occupies a large space, and the practicability is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to ove...
