Problems solved by technology

However, the non-intelligence of the antenna itself has not been resolved
In addition, the gain of the omnidirectional antenna is generally low, and the directional coverage is poor. If there is no precise layout, the terminal signal connection is often unstable.

Abstract

The invention discloses an intelligent dual-frequency antenna system including one or more dual-frequency antenna units. Each dual-frequency antenna unit comprises one or more dual-frequency oscillators, a first frequency band reflection unit and a second frequency band reflection unit on the outer side of the horizontally-polarized dual-frequency oscillator, a first frequency band switch unit corresponding to the first frequency band reflection unit, a second frequency band switch unit corresponding to the second frequency band reflection unit, and a control unit. The system controls on / off of each switch unit to change a radiation direction chart of each dual-frequency antenna unit. Compared with the prior art, the system can flexibly control the antenna radiation direction chart.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of wireless communication, and in particular relates to an intelligent dual-frequency antenna system. [0003] 【Background technique】 [0004] The antenna system is indispensable in the composition of the communication system. In the past wireless communication, a single antenna is used for the transmitting source and the receiving end respectively. This system is called SISO (Single Issue Single Receive). Such systems are prone to multipath effects which can cause problems. When the electromagnetic wave encounters obstacles such as hills, canyons, buildings, wires and cables, problems such as reflection, diffraction, and scattering will occur, so the electromagnetic wave will reach the destination through multiple paths. Delayed scattered signals cause signal fading, dropped calls at the edge (cliff effect) and intermittent reception (like picket fence pattern). In digital communication systems, such as th...
