Problems solved by technology

Although the antenna itself or the antenna configuration can be changed on the tower when required, this effort takes a lot of time, effort and cost to change and optimize the antenna for a specific environment that is not static
In addition, it is difficult to cope with changes in the wave propagation environment and subscriber distribution over time
That is, conventional techniques have limitations such as load balancing and reflecting the communication environment in real time, and there is no specialized technique for steering antenna beams to hotspots

Abstract

A reconfigurable base station (BS) antenna permits increasing cell capacity by dynamically varying an antenna's configuration according to a wave propagation environment and subscriber distribution. At least two reflective plates each have at least one radiator, a ray dome accommodates the two reflective plates in a hollow interior, and upper and lower caps are combined with upper and lower portions of the ray dome, respectively. Reflective connection members are connected to the respective two reflective plates and the upper and lower caps, so that the two reflective plates are rotatable, and at least one force generator provides a rotation force, and at least one force transfer mechanical portion transfers the rotation force received from the force generator to at least one reflective plate and controls a rotation angle of the at least one reflective plate. At least one of the force generator and the force transfer mechanical portion is combined with the two reflective plates.

Description

technical field [0001] The present invention generally relates to a base station (BS) antenna. More particularly, the present invention relates to a BS antenna supporting a multi-antenna scheme and increased transmission capacity in wireless communication. Background technique [0002] With the development of mobile communication technology, the emergence of fourth generation (4G) networks is expected to start operating long before third generation (3G) networks become saturated. The main international standard for 4G networks, Mobile WiMAX or Long Term Evolution (LTE), is trying to maximize the data rate per frequency band, ie increase capacity (bps / Hz) based on multiple antenna technology. Of these, a multiple-antenna technique known as multiple-input multiple-output (MIMO) is currently most effectively used to increase capacity. [0003] For BS antennas, although the multi-antenna technique is based on baseband signal processing, the capacity increase achieved with mult...
