Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Depend on Figure 1 to Figure 5 It can be seen that the MIMO antenna provided in this implementation mainly includes a dielectric substrate 1, four radiating units with identical structures and a metal floor 2. The metal floor is a metal patch structure and is arranged on the back of the dielectric substrate. The four radiating units are folded , are arranged orthogonally to each other around the dielectric substrate, and are fed in a coaxial feeding manner. The MIMO antenna provides radiated energy to the antenna by adding power to the coaxial connector. By using space resources, different antennas perform multi-faceted and multi-directional reception. It can greatly increase or multiply the power without changing the frequency and power. increase the capacity of the communication system.

[0028] The radiation unit is a radiation p...

Abstract

The invention discloses a high-isolation ultra-wideband MIMO antenna suitable for 5G full-band communication, which comprises a dielectric substrate, a metal floor and a radiation unit, wherein the metal floor is arranged on the back surface of the dielectric substrate; the radiation unit comprises a first radiation unit, a second radiation unit, a third radiation unit and a fourth radiation unitwhich are completely the same in structure; the four radiation units are arranged on the periphery of the dielectric substrate in a folding and mutually orthogonal mode; and the four radiation units carry out feeding in a coaxial feeding mode through the four coaxial feeding ports respectively. According to the high-isolation ultra-wideband MIMO antenna suitable for 5G full-band communication, theworking frequency band covers the ultra-wideband frequency band, and has high isolation in the whole frequency band; the radiation units are folded, so that the size of the MIMO antenna is reduced, the MIMO antenna can be placed in a mobile phone for application, and omnidirectional radiation of the antenna is facilitated; and the communication requirements of different frequency bands are met, and the input and output intensity of communication signals is improved.

Description

technical field [0001] The invention relates to antenna technology, in particular to a high-isolation ultra-wideband MIMO antenna suitable for 5G full-band communication, which is mainly used in wireless communication systems. Background technique [0002] In the past few decades, the development of mobile communication from the first generation (1Generation, 1G) voice service to the fourth generation (4generation, 4G) mobile broadband data service, each technological innovation has greatly changed human life. Life has also effectively promoted social development. At present, 4G has been commercialized, and the technology is becoming mature. The fifth generation communication technology (5Generation, 5G) is a new generation of communication technology for new needs in the future. Compared with the traditional fourth generation mobile communication technology, it has higher data The transmission rate and wider bandwidth can greatly improve spectral efficiency. However, 4G m...
