Description

Chamber structure for antenna measurement {A chamber structure for antenna measurement}

The present disclosure relates to a chamber structure for measuring an antenna capable of changing the structure, such as expansion or contraction of the chamber structure.

Recently, with the rapid development of wireless network technology, various communication standards are newly created, and the frequency band of signals used in wireless networks is also widely expanded from MHz to THz.

An antenna is mainly used as a medium for transmitting and receiving radio signals. The characteristics of an antenna can be represented by constant constants such as radiation pattern, efficiency, gain, directivity, polarization, and impedance, and these constant constants are mainly defined and calculated in an ideal free space. However, since it is practically impossible to implement a completely free space, it is preferable to measure the characteristics of an antenna in a space such as an electromagnetic wave anechoic chamber where ambient radio noise is removed as much as possible, which is generally implemented as an anechoic chamber structure.

The size of a general chamber structure for measuring an antenna is predetermined in correspondence with the frequency of a radio signal transmitted and received by an antenna or the size of an antenna. Accordingly, inefficiency arises in that a chamber structure for antenna measurement must be newly manufactured according to the shape and size of the antenna or the frequency of the radio signal.

Accordingly, in the mass production of antennas and industrial sites for measuring antenna performance, there is a need for an antenna measurement chamber structure that can be changed in structure so that antenna performance corresponding to various antenna products can be measured.

A modular chamber structure for antenna measurement according to another embodiment of the present disclosure includes a plurality of first base support members arranged in a first direction; a plurality of second base support members arranged in a second direction different from the first direction; a corner bracket connecting at least one of the first base support members and at least one of the second base support members; and a wall for shielding a radio signal, and the wall may be detachably coupled to at least a portion of the corner bracket, the first base support member, and the second base support member.

According to one embodiment of the present disclosure, a modular chamber structure for measuring an antenna capable of being simply expanded by attaching or detaching an extension structure may be provided.

In addition, according to one embodiment of the present disclosure, a modular chamber structure for antenna measurement that is easy to assemble can be provided because a wireless signal shielding wall made of a lightweight material is attachable and detachable.

It may be connected to the support member 260y. The second expansion brackets 240 are coupled to the other side of the expansion support members 260x and 260y arranged in the first direction and/or the second direction and one side coupled to the first expansion bracket 220, and the second expansion bracket 240 The brackets 240 are connected between two or more base support members 160x and 160y respectively arranged in the first direction and/or the second direction, so that the extension part 200a is coupled to the base parts 100a to 100d.

For example, as shown in FIG. 6 , when the rectangular parallelepiped frame structure 11 is formed, the base support members 160 coupled to the corner bracket 120 may have different lengths. For example, the length of the base support member 160x in the first direction may be shorter than the length of the base support member 160y in the second direction. In this case, the lengths of the extension support members 260x and 260y coupled to the first extension bracket 220 and/or the second extension bracket 240 also correspond to the lengths of the base support members 160 and may be different from each other. For example, the length of the extension support member 260x in the first direction may be shorter than that of the extension support member 260y in the y-axis direction.

When the shape of the chamber structure 10 is determined as required in the industrial field, the shape of the cell 13 can be determined correspondingly, and the support members 160 and 260 coupled to the same brackets 120 , 220 and 240 correspondingly. ) may also be different in length or shape.

12 illustrates a process of extending a frame structure according to an embodiment of the present disclosure in two dimensions.

Referring to FIG. 12 , the frame structure 11 (see FIG. 3 ) according to an exemplary embodiment may be expanded two-dimensionally. For example, the frame structure 11 may be expanded by attaching the extension structure 200 to the base structure 100 .

Also, according to the attachment of the extension structure 200, the number of cells 13 included in the frame structure 11 may increase.

Referring to the drawings as a specific example, in the case of (a), one surface of the frame structure 11 is composed of four square-shaped cells 13a. As described above, the expansion part 200a may be disposed between the base support members 160 constituting several base parts 100a.

According to one embodiment, the frame structure 11 may extend in a first direction (eg, a y-axis direction). The frame structure 11 shown in (a) may further expand in the first direction by combining an additional extension part 200b.

According to another embodiment, the frame structure 11 may extend in the second direction (eg, the x-axis direction). The frame structure 11 shown in (d) and (e) shows the frame structure 11 extended in the second direction. The frame structure 11 shown in (d) is formed by connecting additional extension parts 200d in the x-axis direction in the frame structure 11 shown in (c). By combining the additional expansion part 200d, the frame structure 11 shown in (d) may form additional cells 13d in the x-axis direction. In the frame structure 11 shown in (e), the frame structure 11 may also be expanded by combining additional expansion structures 200e in the x-axis direction, and additional cells 13e may be formed. In addition, the two-dimensional shape of the frame structure 11 may also be transformed into a square. It will be appreciated that in the case of reduction of the frame structure 11, it can be achieved by performing the process opposite to the expansion process described above. The expansion parts 200a, 200b, 200c, 200d, and 200e of various shapes are combined so that the size of the frame structure 11 can be changed, and not only the shape of the frame structure 11 is changed, but also the frame structure 11.

Conversely, when the second extension structures 240 mounted at the corners (edges in the x-axis direction) of the frame structure 11b of (b) are detached and the first extension structures 220 are mounted, the frame structure of (b) (11b) can be scaled like the frame structure (11a) of (a).

As another example, referring to (a) and (c), the first extension attached to two surfaces (eg, two surfaces on the xz plane) of the frame structure 11a of (a) formed perpendicular to the y-axis Brackets (not shown) are replaced with second extension brackets (not shown), so that the size of the frame structure 11a in (a) in the z-axis direction can be reduced as in (c). It will be appreciated that the scaling up of (c) is the reverse of the above process.

Referring to (c) and (d) as another example, similar to the process in which the frame structure 11a of (a) is reduced like the frame structure 11b of (b), the frame structure of (c) ( 11c) is shown reduced like the frame structure 11d in (d).
