Patent Description:
In order to satisfy wireless data traffic demands that tend to increase after <NUM> communication system commercialization, efforts to develop an enhanced <NUM> communication system or a pre-<NUM> communication system are being made. For this reason, the <NUM> communication system or pre-<NUM> communication system is called a beyond <NUM> network communication system or a post LTE system. In order to achieve a high data transfer rate, the <NUM> communication system is considered to be implemented in a mmWave band (e.g., <NUM> band). In order to reduce a propagation path loss and increase the transfer distance of electric waves in the mmWave band, beamforming, massive MIMO, full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming and large scale antenna technologies are being discussed in the <NUM> communication system. Furthermore, in order to improve the network of a system, technologies, such as an improved small cell, an advanced small cell, a cloud radio access network (cloud RAN), an ultra-dense network, device to device communication (D2D), wireless backhaul, a moving network, cooperative communication, coordinated multi-points (CoMP) and reception interference cancellation, are being developed in the <NUM> communication system. In addition, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) that are advanced coding modulation (ACM) schemes, improved filter bank multi-carrier (FBMC), non-quadrature multiple access (NOMA) and sparse code multiple access (SCMA) are being developed in the <NUM> system.

The Internet evolves from a human-centered connection network over which human generates and consumes information to Internet of Things (IoT) through which information is exchanged and processed between distributed elements, such as things. An Internet of Everything (IoE) technology in which a big data processing technology through a connection with a cloud server is combined with the IoT technology is emerging. In order to implement the IoT, technical elements, such as the sensing technology, wired/wireless communication and network infrastructure, service interface technology and security technology, are required. Accordingly, technologies, such as a sensor network, machine to machine (M2M) and machine type communication (MTC) for a connection between things, are recently researched. In the IoT environment, an intelligent Internet technology (IT) service in which a new value is created for human life by collecting and analyzing data generated from connected things may be provided. The IoT may be applied to fields, such as a smart home, a smart building, a smart city, a smart car or a connected car, a smart grid, health care, smart home appliances, and advanced medical services, through convergence and composition between the existing information technology (IT) and various industries.

Prior art publications of <CIT>, <CIT>, <CIT> and <CIT> each refers an antenna having a top side and a second side formed at an angle to the top side wherein antenna radio signal is emitted via an aperture extending from the top side to the second side.

Further prior art of <CIT> (belongs to the state of the art under Article <NUM>(<NUM>) EPC), <CIT>, <CIT>, <CIT> each refers to a multilayer antenna having a slot, in which a power feeding part is positioned.

Accordingly, various attempts to apply the <NUM> communication system to the IoT are being made. For example, <NUM> communication technologies, such as a sensor network, machine to machine (M2M) and machine type communication (MTC), are implemented by schemes, such as beamforming, MIMO, and an array antenna. The application of a cloud wireless access network (cloud RAN) as the aforementioned big data processing technology may be said to be an example of convergence between the <NUM> technology and the IoT technology.

As described above, in the <NUM> communication system, a propagation path loss is great. Accordingly, the structure of an antenna module using <NUM> communication is inevitably different from the antenna module structure of the <NUM> communication system.

A scheme taken into consideration in order to overcome the propagation path loss is the structure of an antenna module for generating a vertically polarized wave. In the <NUM> communication system, smooth communication can be performed between a terminal and a base station through only a horizontally polarized wave. In contrast, in the <NUM> communication system using an ultra-high frequency, smooth communication cannot be performed between a terminal and a base station through only a horizontally polarized wave.

Accordingly, the disclosure proposes an antenna module structure capable of generating a vertically polarized wave for solving the problem.

An embodiment of the disclosure provides an antenna module, including a multi-layered layer in which a plurality of layers is stacked, a slot being formed in one side of the multi-layered layer and a first power feeding part positioned in the slot as per the appended claims.

According to the disclosure, a vertically polarized wave can be generated through the antenna module. Particularly, a vertically polarized wave can be generated even in a structure by which it is difficult to generate a vertically polarized wave due to a narrow width, such as the end of a terminal.

In general, a radio wave radiated through an antenna travels in the state in which an electric field and a magnetic field are orthogonal to each other. A radio wave whose electric field is vertical to the ground is called a vertically polarized wave. In contrast, a radio wave whose electric field is horizontal to the ground is called a horizontally polarized wave.

According to one embodiment, a vertical polarization antenna or horizontal polarization antenna may be formed through a patch antenna. For example, a vertical polarization antenna may be formed through a patch antenna vertical to the ground. A horizontal polarization antenna may be formed through a patch antenna horizontal to the ground.

Recently, an electronic device (including a smartphone and a terminal) tends to have its size gradually reduced. Particularly, the thickness of the electronic device continues to be reduced. Accordingly, a horizontal polarization antenna can be mounted on the electronic device, but a vertical polarization antenna cannot be mounted on the electronic device due to a low thickness.

For this reason, there is a need for an antenna structure capable of generating a vertically polarized wave in a structure on which it is difficult to mount a patch type vertical polarization antenna, such as the end of an electronic device. The disclosure is intended to provide an antenna structure for solving such a problem.

<FIG> illustrates an antenna module structure capable of generating a vertically polarized wave toward the end of an electronic device according to an embodiment of the disclosure.

An antenna module <NUM> according to an embodiment of the disclosure may include a first plate <NUM> configuring the top side of the antenna module and a second plate <NUM> configuring the side of the antenna module <NUM> and neighboring the first plate <NUM> to form a first angle along with the first plate <NUM>. According to one embodiment, the first plate <NUM> may face the top side of an electronic device, and the second plate <NUM> may face the side of the electronic device.

A first aperture <NUM> may be formed in one side of the first plate. A second aperture <NUM> may be formed in one side of the second plate <NUM> so that the first aperture <NUM> extends.

According to one embodiment, an opening part having a given shape (rectangular parallelepiped shape in <FIG>) may be formed in the antenna module <NUM> by the first aperture <NUM> and the second aperture <NUM>.

According to one embodiment, a power feeding unit <NUM> is electrically connected to the first plate <NUM> and may be exposed to the outside through the first aperture <NUM> and the second aperture <NUM>. The power feeding unit <NUM> may be electrically connected to a communication circuit (not illustrated). The power feeding unit <NUM> may receive an electric current from the communication circuit and radiate a radio wave having a given frequency.

According to one embodiment, the power feeding unit <NUM> may include a first power feeding part <NUM> formed in parallel to the first plate and a second power feeding part <NUM> formed in parallel to the second plate. The first power feeding part <NUM> and the second power feeding part <NUM> may be electrically connected by forming the first angle. According to one embodiment, the first power feeding part <NUM> and the second power feeding part <NUM> may be formed at an angle of <NUM>°.

According to one embodiment, a radio wave may be selectively radiated in the direction of the first plate <NUM> or in the direction of the second plate <NUM> by controlling an electric current flowing into the first power feeding part <NUM> or the second power feeding part <NUM>.

For example, as disclosed in <FIG>, if only an electric current flowing into the second power feeding part <NUM> is excited, a radio wave may be radiated only in the direction of the second plate <NUM>. Furthermore, in this case, the radio wave radiated in the direction of the second plate <NUM> may be a vertically polarized wave. A vertically polarized wave may be generated through a structure, such as that illustrated in <FIG>. This is described later with reference to <FIG> and <FIG>.

According to one embodiment, an opening part may be formed by removing the plating of a first face corresponding to the first aperture and a second face corresponding to the second aperture in a plated antenna module structure.

According to one embodiment, a current vector having a given shape is formed in the opening part by applying an electric current to the power feeding unit <NUM> positioned in the opening part. Accordingly, an electric field vertical to the ground may be formed.

<FIG> illustrates an antenna module structure capable of generating a vertically polarized wave toward the top side of an electronic device according to an embodiment of the disclosure.

The antenna module structure illustrated in <FIG> is the same as that illustrated in <FIG>. In this case, in <FIG>, a communication circuit may excite only an electric current flowing into the first power feeding part <NUM>. Accordingly, the antenna module <NUM> may radiate a radio wave only in the direction of the first plate <NUM>.

The remaining antenna module elements disclosed in <FIG> may be the same or similar to the remaining antenna module elements disclosed in <FIG>.

<FIG> illustrates an antenna module structure capable of generating a vertically polarized wave according to an embodiment of the disclosure.

An antenna module <NUM> according to the disclosure may have a structure in which a plurality of layers has been stacked. For example, the antenna module may be a printed circuit board (PCB) in which a plurality of insulation layers has been stacked. A slot <NUM> may be formed in one side <NUM> of the multi-layered layer <NUM> in which the plurality of layers has been stacked.

The slot <NUM> may be formed only in some of the plurality of layers. For example, the slot may be continuously extended and formed from one side <NUM> of the topmost layer <NUM> of the multi-layered layer <NUM> to one side of a preset layer.

According to one embodiment, a slot having the same shape may be formed in one side <NUM> up to the third layer downward from the topmost layer <NUM> of the multi-layered layer <NUM>. The slot may not be formed from the fourth layer to the lowest layer downward from the topmost layer <NUM>.

According to one embodiment, a power feeding unit <NUM> may be positioned in the slot <NUM>. The power feeding unit <NUM> may be positioned along the outskirts of the multi-layered layer <NUM>. A more detailed shape of the power feeding unit <NUM> is described later through a description of <FIG>.

When an electric current is applied to the power feeding unit <NUM>, the vectors of the electric current (J surface current) are distributed along the slot <NUM> that surrounds the power feeding unit <NUM>, so a vertically polarized wave may be radiated in the direction of one side <NUM> of the multi-layered layer <NUM>. Accordingly, the frequency characteristic of a radio wave radiated through the antenna module including the multi-layered layer <NUM> may be determined based on the size and shape of the slot <NUM>. This is described later through a description of <FIG>.

According to one embodiment, a reflector <NUM> positioned within the multi-layered layer <NUM> and spaced apart from the power feeding unit <NUM> by a preset distance may be further included. The reflector <NUM> can improve a gain value of the antenna module by reflecting a radio wave, radiated toward the inside of the multi-layered layer <NUM>, toward the outside of one side <NUM> of the multi-layered layer <NUM>.

According to one embodiment, the reflector <NUM> may have various shapes. Furthermore, the distance between the reflector <NUM> and the power feeding unit <NUM> that radiates a radio wave may be determined based on a frequency that is to be radiated through the power feeding unit <NUM>.

According to one embodiment, a ground pad <NUM> may be positioned in the topmost layer <NUM> of the multi-layered layer <NUM>. For example, mounting between the multi-layered layer <NUM> and a communication circuit may be facilitated by positioning, in the topmost layer <NUM>, a ground signal ground (GSG) pad using a coaxial method. According to one embodiment, the power feeding unit <NUM> may be electrically connected to the ground pad <NUM>.

The antenna module structure disclosed in <FIG> is merely an embodiment, and thus the scope of the disclosure should not be limited to the antenna module structure disclosed in <FIG>. For example, two or more power feeding units <NUM> may be disposed in the slot <NUM>.

<FIG> is a diagram illustrating a side view of the antenna module structure illustrated in <FIG>, which is taken in a direction AA'.

<FIG> is a diagram illustrating a case where the multi-layered layer <NUM> is configured with <NUM> layers. The slot may be formed up to the third layer downward from the topmost layer <NUM> of the multi-layered layer <NUM>. In contrast, the slot <NUM> may not be formed from the fourth layer to the sixth layer downward from the topmost layer <NUM>. That is, the multi-layered layer <NUM> according to the disclosure may be divided into a layer area <NUM> in which the slot is formed and a layer area <NUM> in which the slot is not formed.

According to one embodiment, the power feeding unit <NUM> may be positioned in the layer area <NUM> in which the slot is formed. The power feeding unit <NUM> may be electrically connected to a ground pad <NUM>, positioned in the topmost layer <NUM>, in the first layer downward from the topmost layer <NUM>.

Furthermore, the power feeding unit <NUM> may be extended toward one side of the multi-layered layer <NUM> in which the slot has been formed in the first layer downward from the topmost layer <NUM>, thus forming a first power feeding part. The power feeding unit <NUM> may be bent by <NUM>° at the end of the first power feeding part and may be extended up to the third layer downward from the topmost layer <NUM>, thus forming a second power feeding part (the power feeding unit <NUM> is described as being divided into the first power feeding part and the second power feeding part, but the first power feeding part and the second power feeding part may be one element). According to one embodiment, impedance matching of the antenna module may be implemented based on the length of the power feeding unit <NUM>.

The antenna module structure disclosed in <FIG> and the antenna module structure disclosed in <FIG> and <FIG> may be associated. For example, if an electric current is excited in the second power feeding part extended from the first layer to the third layer downward from the topmost layer <NUM> in <FIG>, this may lead to the antenna module radiation structure disclosed in <FIG>. If an electric current is excited in the first power feeding part, this may lead to the antenna module radiation structure disclosed in <FIG>.

The reflector <NUM> may be spaced apart from the power feeding unit <NUM> by a preset distance and positioned. A radio wave radiated from the power feeding unit <NUM> toward the radiator <NUM> may be reflected by the reflector <NUM>. A radio wave reflected by the reflector <NUM> may be radiated to the outside of the antenna module through the layer area <NUM> in which the slot has been formed. According to one embodiment, the layer area <NUM> in which the slot has not been formed may be configured as a ground layer.

<FIG> is a diagram illustrating the state in which the antenna module structure illustrated in <FIG> has been viewed from the top.

The slot <NUM> may be formed in one side of the topmost layer <NUM>. The slot <NUM> may have a rectangle shape having a base "a" and a height "b. " According to one embodiment, edges on both sides of the rectangle shape may have rounds through tapering processing in order to minimize the internal reflection of a radio wave.

As disclosed above, the frequency characteristic of a radio wave radiated through the slot <NUM> may be determined based on the size of the slot <NUM>. For example, the value "a" may be determined based on a resonant frequency value of the antenna module. The value "b" may be determined based on an impedance bandwidth of the antenna module. According to one embodiment, the value "a" may be greater than the value "b.

According to one embodiment, the ground pad <NUM> may be positioned in the topmost layer <NUM>. The ground pad <NUM> may be positioned in a hole formed in the topmost layer <NUM>. <FIG> illustrates a case where the ground pad <NUM> and the hole have been formed in a circle shape, but the scope of the disclosure should not be limited thereto. The ground pad <NUM> and the hole may have various shapes.

<FIG> is a diagram illustrating an electric field distribution of the antenna module structure disclosed in <FIG>.

According to the antenna module structure disclosed in the disclosure, an electric field vertical to the ground may be formed. Accordingly, a vertically polarized wave may be radiated. An antenna module according to an embodiment of the disclosure can generate a vertically polarized wave even without a patch antenna vertical to the ground. Accordingly, the antenna module according to an embodiment of the disclosure can efficiently generate a vertically polarized wave although a space is narrow as in the end of an electronic device.

It may be seen that the antenna module structure disclosed in <FIG> is an antenna module structure for generating a vertically polarized wave because a vertically polarized wave has a greater gain value than a horizontally polarized wave as disclosed in <FIG>. Furthermore, it may be seen that the vertically polarized wave has about <NUM> dB a greater gain value than the horizontally polarized wave even at the end of the antenna module (or the end of an electronic device, a direction whose phase is <NUM>° in <FIG>).

<FIG> illustrates an antenna module structure capable of generating a horizontally polarized wave according to an embodiment of the disclosure.

As disclosed in <FIG>, a horizontally polarized wave may be generated by disposing a plurality of patch antennas <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> in respective layers configuring a multi-layered layer <NUM>.

A slot antenna has been used in a vertically polarized wave as described above because it is impossible to dispose patch antennas in the direction vertical to the multi-layered layer <NUM>. However, a horizontally polarized wave may be generated using the plurality of patch antennas <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> because the patch antennas can be disposed in the direction horizontal to the multi-layered layer <NUM>.

According to one embodiment, the plurality of patch antennas <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> may be spaced apart from one side <NUM> of the multi-layered layer <NUM> by a preset distance and positioned. Furthermore, the plurality of patch antennas <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> may be interconnected through a via.
