Patent Description:
To meet the demand for wireless data traffic having increased since deployment of <NUM> communication systems, efforts have been made to develop an improved 5th generation (<NUM>) or pre-<NUM> communication system. The <NUM> or pre-<NUM> communication system may also be referred to as a 'Beyond 4th generation (<NUM>) Network' or a 'Post LTE System'. In the <NUM> system, Hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) Modulation (FQAM) and sliding window superposition coding (SWSC) as an advanced coding modulation (ACM), and filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as an advanced access technology have been developed.

The Internet, which may refer, for example, to a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of Things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of Everything (IoE), which is a combination of the loT technology and the Big Data processing technology through connection with a cloud server, has emerged. As technology elements, such as "sensing technology", "wired/wireless communication and network infrastructure", "service interface technology", and "Security technology" have been demanded for loT implementation, a sensor network, a Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and so forth have been recently researched. Such an loT environment may provide intelligent Internet technology services that create a new value to human life by collecting and analyzing data generated among connected things. loT may be applied to a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services through convergence and combination between existing Information Technology (IT) and various industrial applications.

In line with this, various attempts have been made to apply <NUM> communication systems to loT networks. Application of a cloud RAN as the above-described Big Data processing technology may also be considered to be as an example of convergence between the <NUM> technology and the loT technology. Document (<CIT>) discloses a RF transparent window of a portable electronic device, for example, laptop or any other hand-held electronic device such as a smart phone. Document (<CIT>) discloses an electronic device which increases transmission/reception efficiency by using a distance between an antenna and a peripheral component.

As described above, due to sensitivity to radio environments in ultra-high frequency bands, it is necessary, when base stations are implemented in a <NUM> communication system, to review various factors ranging from the material of covers to the thickness thereof in advance.

Particularly, currently used covers for ultra-high frequency bands are sensitive to the permittivity and dielectric loss of the material used for the covers, and it is thus necessary to optimize the material and thickness of the covers according to the frequency band of beams emitted from antennas. That is, when base stations are implemented in an existing <NUM> communication system supporting ultra-high frequency bands, the optimized material or thickness of covers may vary depending on each frequency band. As a result, cover molds having the material or thickness optimized for each frequency band are fabricated, respectively.

Embodiments of the disclosure relate to a cover device having a functional structure which has a material optimized for a single- or multi-frequency band, and which is positioned on a cover frame fabricated using a common mold, such that the same can have an optimal performance flexibly for each of various frequency bands.

Embodiments of the disclosure may provide a functional structure that may have one or more functional layers implemented in a multilayered form such that the same can be implemented as a structure that minimizes and/or reduces distortion of beams from a single antenna or multiple antennas capable of controlling at least one of strength, permittivity, magnetic permeability, or conductivity.

According to an aspect of the disclosure, a cover device of a base station communicating with a terminal is provided as defined by the appended claims.

A cover device according to various example embodiments may include a functional structure having a stacked structure including one or more functional layers capable of minimizing and/or reducing distortion of beams in a single-or multi-frequency band emitted from an antenna device.

A cover device according to various example embodiments may include a functional structure having one or more functional layers implemented in a multilayered form such that at least one of strength, permittivity, magnetic permeability, or conductivity can be controlled. Accordingly, the same may have a material optimized for a single- or multi-frequency band. As a result, there may be no need to implement a cover device using a separate mold such that the same has a material or thickness optimized for each frequency band as in the prior art.

Accordingly, a cover device according to various example embodiments may have a functional structure positioned on a cover frame, the functional structure having a stacked structure including one or more functional layers, such that the same includes a material optimized for a single- or multi-frequency band having a predetermined thickness without having to fabricate a new mold for an antenna cover device having a material or thickness optimized for each frequency band when base stations having the same exterior are implemented. As a result, distortion of beams in a single- or multi-frequency band radiated from the antenna device can be minimized and/or reduced.

Various example embodiments of the disclosure will be described in greater detail below in conjunction with the accompanying drawings. However, the disclosure is not limited to the example embodiments set forth below, and may be implemented in various different forms. Throughout the disclosure, the same or like reference numerals designate the same or like elements.

In the following description of the disclosure, a detailed description of known functions or configurations incorporated herein may be omitted when it may make the subject matter of the disclosure unnecessarily unclear. The terms which will be described below are terms defined in consideration of the functions in the disclosure, and may be different according to users, intentions of the users, or customs. Therefore, the definitions of the terms should be made based on the contents throughout the disclosure.

<FIG> is a diagram illustrating a base station device for an ultra-high frequency band.

As illustrated in <FIG>, a base station device <NUM> includes an antenna device <NUM> configured to radiate a beam of an ultra-high frequency band to the interior of a base station, and a cover device <NUM> configured to protect the antenna device <NUM> from an external environment.

<FIG> is a diagram illustrating the material or the thickness of an antenna cover device.

As described above, a <NUM> communication system is sensitive to an electric wave environment at an ultra-high frequency band, and thus it is necessary to variously review both the material and the thickness of a cover in advance when a base station is implemented.

For example, because the cover device for an ultra-high frequency band is sensitive to the permittivity and the dielectric loss of the material of a cover even in the case of the same external shape when a base station is implemented, It is necessary to optimize the material and the thickness of the cover device according to the band of an antenna. That is, the material or the thickness of the cover device that is optimized for frequency bands when a base station is implemented in a <NUM> system that currently supports an ultra-high frequency band may become changed, and thus cover molds having materials or thicknesses that are optimized for frequency bands are manufactured, respectively.

According to various embodiments, the characteristics of the optimal thickness and the optimal material of an antenna cover device that minimizes and/or reduces distortion of a beam radiated from an antenna device may be changed according to a frequency band.

In the cover device having the same thickness according to various embodiments, the characteristics of the material that minimizes and/or reduces distortion of a beam may be changed according to a frequency band.

As illustrated in <FIG>, in the cover device having a predetermined thickness d, the characteristics of the material that minimizes and/or reduces distortion of a beam may be changed according to a frequency band.

The characteristics of the materials of the cover device <NUM> may be different when the frequency band of a beam radiated from the antenna device embedded in the base station device is <NUM> and <NUM>.

The characteristic of the material according to various embodiments may include one or more characteristics of the strength, the permittivity, the magnetic permeability, or the conductivity.

The characteristics of the material of the cover device that are optimal according to the frequency band of a beam radiated from the antenna device described in the specification pertain to one embodiment derived according to various simulation results, and the disclosure is not limited thereto.

In the cover device having characteristics of the same material according to the disclosure, the thickness that minimizes and/or reduces distortion of a beam may be changed according to a frequency band.

For example, as illustrated in <FIG>, the optimal thickness d of the cover device may be <NUM> when the frequency band of a beam radiated from the antenna device embedded in the base station device is <NUM>, and the optimal thickness d of the cover device <NUM> having characteristics of the same material may be <NUM> when the frequency band of the beam is <NUM>.

The thickness of the cover device that is optimal according to the frequency band of a beam radiated from the antenna device described in the specification pertains to one embodiment derived according to various simulation results, and the disclosure is not limited thereto.

Conventionally, cover devices for ultra-high frequency bands are produced for respective bands only by manufacturing molds of the cover devices having optimal thicknesses corresponding to the optimal materials for the frequency bands.

For example, when the materials of the cover devices are the same, it is necessary to manufacture a radome mold for <NUM> having a thickness of <NUM>, a radome mold for <NUM> having a thickness of <NUM>, and the like, respectively.

As illustrated in <FIG>, the thickness of a central portion <NUM> of the cover device <NUM> may be different from or the same as the thickness of a side surface part <NUM> of the cover device <NUM>.

The window area <NUM> according to an embodiment may correspond to a radiation area of the antenna in the base station device, and may be changed according to the location and the extent of the antenna device embedded in the base station device. For example, the window area may be located in at least one area of an upper end portion, a lower end portion, a front surface portion, and a side surface portion of the cover frame. This will be described in greater detail below with reference to <FIG>, <FIG> and <FIG>.

As illustrated in <FIG>, a functional structure <NUM> of a stacked structure including one or more functional layers is located in the opened window area <NUM> located in the cover frame <NUM> according to an embodiment, whereby a cover device <NUM> having characteristics of a material that is optimized for a single frequency band or multiple frequency bands is implemented. For example, the functional structure <NUM> can minimize and/or reduce distortion of a beam radiated from the antenna device embedded in the base station device as illustrated in <FIG> below even when the frequency band of the beam is <NUM> or <NUM>.

Accordingly, in the cover device according to various embodiments, by locating the functional structure having characteristics of the material that is optimized for a single frequency band or multiple frequency bands in one cover frame, the cover devices for frequency bands may be implemented by one device or shared when the base station having the same external shape is implemented.

The window area <NUM> included in the cover frame according to an embodiment may correspond to a radiation area of the antenna in the base station device, and may be changed according to the location and the extent of the antenna device embedded in the base station device.

Because the one or more functional layers having characteristics of various strengths, various permittivities, various magnetic permeabilities, or various conductivities are implemented in a multilayered form, one or more material characteristics, such as strength, permittivity, magnetic permeability, or conductivity can be controlled, and thus the functional structure <NUM> according to various embodiments can have characteristics of the material that is optimized for a single frequency band or multiple frequency bands.
