Description

Beam coverage expansion antenna and structure including the same {A STRUCTURE EQUIPPED WITH ANTENNAS FOR BEAM COVERAGE EXPANSION}

The present invention relates to wireless communication, and more specifically, to a beam coverage expansion antenna and a structure including the same.

Wireless communication technology for transmitting and receiving information continues to develop. Among them, an antenna device is required to transmit or receive signals for wireless communication, and various types and methods of antenna devices have been developed to achieve higher performance. Recently, technologies have been developed to overcome performance limitations that are difficult to achieve with a single antenna, such as MIMO antennas, and beam forming technology to control the radiation direction of the signal to maximize the strength of the transmitted and received signals between the base station and the terminal. This was also developed.

In particular, recent wireless communication technologies, such as 3GPP 5G, have begun to use frequencies in the millimeter wave (mmWave) band, and the mmWave band wireless channel environment has the characteristics of free space path loss and diffraction reduction, leading to signal attenuation. In order to solve the problem that may occur, beam forming technology using phased array antennas is being applied more importantly. Such beam forming technology is required for both base stations and terminals, and is especially essential for securing wide coverage and overcoming propagation loss in a mobile wireless channel environment.

However, there may be limitations in expanding beam coverage simply by controlling the directivity of transmitted and received signals based on beam forming. Beam forming for wireless signals can be achieved by differently controlling the phase and/or size of the signals of a plurality of radiators. Directional control of the transmitted and received signals sufficient to overcome the orientation of the radiator arrays itself can be achieved through software beam forming. It is difficult to achieve this through foaming alone.
