Problems solved by technology

[0004] Most of the smart antennas currently in use are composed of antenna arrays, which form different radiation patterns by changing the amplitude and phase of each antenna unit, but such antenna arrays are generally only adaptively adjusted in a specific sector. Unable to meet 360-degree omnidirectional coverage requirements
Difficult to meet coverage requirements without a very precise layout

Abstract

The invention provides a multi-mode conical antenna system applied to WIFI, which comprises a substrate and an antenna unit connected with the substrate, wherein the antenna unit is composed of four independent antennas, and each independent antenna is provided with an independent switch. Through controlling switching on and switching off of the switch, a specific radiation pattern is formed, and a better wireless link is provided for communication equipment. Compared with the prior art, the antenna system has a small size, the working frequency band is wide, the radiation pattern can be changed, the cost is lower, and manufacturing is easier.

Description

technical field [0001] The invention belongs to the field of antennas, and specifically relates to a group of four independent antennas forming a cone-shaped antenna unit. Through electronic control of each independent antenna, a specific radiation pattern has been formed, which can adapt to the environment and provide reliable transmission and reception equipment. , Efficient communication links. Background technique [0002] 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 input single output, ie: single send 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 electrom...
