This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0132033, filed on Oct. 4, 2023, the disclosure of which is incorporated herein by reference in its entirety.
The present invention relates to a communication line, and more particularly, to a communication line for signal transmission.
Communication lines made of dielectrics have a lower manufacturing cost than conductor-based communication lines and their installation and management are easier than optical-based communication lines, hereby efficiently utilizing the communication lines in chip-to-chip communications.
However, conventional communication lines have a problem in that an amount of the outside leakage of signals propagating in the conventional communication lines is excessive. Accordingly, the signals propagating through the conventional communication lines become incomplete, and as the length of the communication line increases, the attenuation of the signal may increase, cumulative signal loss may increase, and noise may be generated in electronic devices around the communication line.
Further, chip-to-chip communication may be performed in enclosed spaces such as server cases or computer cases, and in this case, excessive force is required to bend conventional communication lines. Accordingly, the conventional communication lines have the problem in that the conventional communication lines are difficult to be used in narrow or complex spaces because their shapes are not easily changed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
First, referring to
The core portion 1100 may include a dielectric core 1110 and a first supporter portion 1120.
The dielectric core 1110 may be formed to be located inside the shielding portion 1200 and extend in the longitudinal direction. The longitudinal direction may be a Z-axis direction illustrated in
The dielectric core 1110 may have a hollow tubular shape. For example, a central hole 1111 may be formed inside the dielectric core 1110. Further, an outer surface of the dielectric core 1110 and the central hole 1111 may have a circularly extended shape. In this case, as illustrated in
Meanwhile, permittivity is a value for the effect of a medium between charges on an electric field when the electric field acts between the charges, and depends on the frequency of an electromagnetic wave signal propagating in a dielectric. Further, when an electromagnetic wave signal propagates toward a boundary between materials having different permittivities, the electromagnetic wave signal may be adjusted to be totally reflected at the boundary between the two materials by adjusting permittivity, a signal incident angle of each of the two materials, or a frequency of the signal. Accordingly, by utilizing the above-described characteristics, the electromagnetic wave signal received at one end of the dielectric core 1110 in the communication line 1000 according to the embodiment of the present invention may be transmitted to the other end of the dielectric core 1110 in the longitudinal direction thereof.
Meanwhile, a material of the dielectric core 1110 may be a material having a higher permittivity than the air has. The electromagnetic wave signal transmitted through the dielectric core 1110 may be totally reflected inside the dielectric core 1110 without externally leaking to an air layer 1400. That is, according to the embodiment of the present invention, the air layer 1400 may prevent the electromagnetic wave signal transmitted through the dielectric core 1110 from leaking out of the dielectric core 1110. The air layer 1400 may be formed inside a shielding 1210 of the shielding portion 1200. The air layer 1400 may include the air or a dielectric different from the dielectric core 1110.
Here, the air layer 1400 may be filled with a dielectric material having a different permittivity from the permittivity of the material of the dielectric core 1110. For example, the air layer 1400 may be filled with a flexible dielectric material.
Meanwhile, in the communication line 1000 according to an embodiment of the present invention, the core portion 1100, the shielding portion 1200, and the rib 1300 may be made of the same dielectric material. In this case, since the permittivity is the same in all portion of the communication line 1000, the frequency of the signal may be easily adjusted so that the signal transmitted through the dielectric core 1110 does not leak to the air layer 1400.
In some cases, in the communication line 1000 according to an embodiment of the present invention, the core portion 1100, the shielding portion 1200, and the rib 1300 may be made of the same flexible dielectric material. In this case, since the force required for bending is the same in all portion of the communication line 1000, the shape of the communication line 1000 may be easily changed. Accordingly, even in a narrow space, the communication line 1000 may be installed in various shapes to connect a chip to a chip. Further, since the central hole 1111 is formed inside the dielectric core 1110, the communication line 1000 may be flexibly bent with a small force.
Meanwhile, the first supporter portion 1120 may be formed to extend on the outer surface of the dielectric core 1110. The first supporter portion 1120 may include a first support member 1121 and a protruding member 1122. In one embodiment, the first supporter portion 1120 may include only the first support member 1121. The number of first supporter portions 1120 may be one or more.
The first support member 1121 may be formed to extend on the outer surface of the dielectric core 1110. The first support member 1121 may be located between the dielectric core 1110 and the protruding member 1122 to fix the protruding member 1122 to the dielectric core 1110.
The protruding member 1122 may be formed to extend on an outer surface of the first support member 1121. For example, the protruding member 1122 may be formed on one surface of the first support member 1121 that is opposite to the other surface of the first support member 1121 in contact with the dielectric core 1110.
The protruding member 1122 may come into contact with a second supporter portion 1220 of the shielding portion 1200 when physically deformed. A detailed description thereof will be described below with reference to
The protruding member 1122 may have a shape with a circular cross section. However, the shape of the protruding member 1122 is not limited thereto. For example, the cross section of the protruding member 1122 may be a polygonal shape. For another example, the protruding member 1122 may have the same shape as the rib 1300.
Meanwhile, the shielding portion 1200 may include the shielding 1210 and the second supporter portion 1220.
The shielding 1210 may have a hollow tubular shape. Therefore, the core portion 1100 may be formed inside the shielding portion 1200, that is, inside the shielding 1210.
The second supporter portion 1220 may be formed to extend on an inner circumferential surface of the shielding 1210 to correspond to the first supporter portion 1120. The number of second supporter portions 1220 may correspond to the number of first supporter portions 1120.
The second supporter portion 1220 may be formed at a location where the second supporter portion 1220 comes into contact with the first supporter portion 1120 when physically deformed. That is, the first supporter portion 1120 and the second supporter portion 1220 may be formed to be spaced apart from each other, and may come into contact with each other only when physically deformed. Since the first supporter portion 1120 and the second supporter portion 1220 come into contact with each other when physically deformed, the shape of the shielding 1210 is not deformed within a certain degree, thereby minimizing transmission loss in the communication line 1000.
The second supporter portion 1220 may include a second support member 1221 and a buffer member 1222.
The second support member 1221 may be formed to extend on an inner surface of the shielding 1210. The second support member 1221 may be located between the shielding 1210 and the buffer member 1222 to fix the buffer member 1222 to the shielding 1210.
The buffer member 1222 may be formed to extend on an outer surface of the second support member 1221. For example, the buffer member 1222 may be formed on one surface of the second support member 1221 that is opposite to the other surface of the second support member 1221 in contact with the shielding 1210.
The buffer member 1222 may come into contact with the protruding member 1122 of the first supporter portion 1120 when physically deformed. A detailed description thereof will be described below with reference to
A shape and area of the buffer member 1222 may be determined based on the number of first supporter portions 1120. When a physical impact is applied to the communication line 1000, the rib 1300 and the dielectric core 1110 are shaken, and the buffer member 1222 may support the first supporter portion 1120 so that the first supporter portion 1120 does not shake excessively. Therefore, the buffer member 1222 may have a shape and an area to prevent the shaking of the first supporter portion 1120.
Further, the shape and the area of the buffer member 1222 for preventing the shaking of the first supporter portion 1120 may be determined based on the number of first supporter portions 1120 provided in the communication line 1000. For example, as illustrated in
For another example, as illustrated in
Meanwhile, the buffer member 1222 may have a straight or curved shape so that the buffer member 1222 comes into smooth contact with the protruding member 1122 of the first supporter portion 1120 when physically deformed. For example, the buffer member 1222 may have a U-shaped curved shape that surrounds the protruding member 1122.
Meanwhile, a direction in which the first supporter portion 1120 is formed in the dielectric core 1110 and a direction in which the second supporter portion 1220 is formed on the inner circumferential surface of the shielding 1210 may be opposite to each other. Here, the opposite may mean a view in a 180° direction. That is, the first support member 1121 of the first supporter portion 1120 and the second support member 1221 of the second supporter portion 1220 may be present on the same straight line. Therefore, when physically deformed, the second supporter portion 1220 may more firmly sustain the force received from the first supporter portion 1120 without deformation.
The rib 1300 may be located between the shielding portion 1200 and the core portion 1100 and connect the shielding portion 1200 and the core portion 1100. The rib 1300 may be formed on the outer surface of the dielectric core 1110. For example, the rib 1300 may be formed to extend in the longitudinal direction on the outer surface of the dielectric core 1110. In an embodiment of the present invention, the number of ribs 1300 may be one. Therefore, in the communication line 1000, by minimizing the number of ribs 1300 connected to the dielectric core 1110, the magnetic field emitted to the outside from the dielectric core 1110 may be minimized. Further, in the communication line 1000, the number of ribs 1300 can be minimized, and thus bending freedom degree and easiness can be increased.
Meanwhile, as illustrated in
Meanwhile, the core portion 1100, the shielding portion 1200, and the rib 1300 may be made of a dielectric material and formed integrally. In this case, a manufacturing process of the communication line 1000 may be greatly simplified, thereby reducing the manufacturing cost and time. For example, the communication line 1000 may be manufactured through only one injection molding process using one dielectric material.

For example, the antenna 660a may be connected to a signal generating portion disposed on a chip and may guide a signal output from the signal generating portion toward one end of the communication line 1000. In this case, the antenna 660a may serve as a waveguide that imparts directionality to a wireless signal or adjusts the direction of the signal.
