Abstract

Disclosed is a wireless communication system. The wireless communication system includes an embedded-type antenna embedded in a base, and a wireless communication unit including a communication unit that is connected to the embedded-type antenna and exchanges information with an external device, and a housing that is arranged to surround the communication unit, wherein at least one of the communication unit and the housing performs transmission and reception of electric waves as a substitute of the embedded-type antenna.

Claims

1. A wireless communication system comprising:

an embedded-type antenna embedded in a base; and

a wireless communication unit including a communication unit that is connected to the embedded-type antenna and exchanges information with an external device, and a housing that is arranged to surround the communication unit, wherein at least one of the communication unit and the housing performs transmission and reception of electric waves as a substitute of the embedded-type antenna;

wherein the embedded-type antenna has a lower side in contact with the base and an upper side not in contact with the base, and the wireless communication unit is disposed on the upper side of the embedded-type antenna, and the embedded-type antenna is disposed between the base and the wireless communication unit, such that the wireless communication unit is supported by the embedded-type antenna and the wireless communication unit is fixed to the base by the embedded-type antenna;

wherein the communication unit includes a communication module that performs overall control of the communication unit, a first cable that connects the communication module to the embedded-type antenna, and a second cable that connects the communication module to an internal side of the housing.

2. The wireless communication system of claim 1, wherein the housing includes a first connection unit, and the communication unit includes a communication module disposed at an internal space of the first connection unit,

wherein the embedded-type antenna includes:

an antenna housing whose lower part is formed in a cone shape and is embedded in the base;

a matching unit that is arranged at an upper part of the antenna housing and performs impedance matching;

a connection pin passing through the matching unit from an upper end of the antenna housing, the connection pin being inserted into the connection module; and

a second connection unit coupled with the first connection unit, the second connection unit having a diameter larger than a diameter of the first connection unit.

3. The wireless communication system of claim 2, wherein the matching unit includes a dielectric.

4. The wireless communication system of claim 1, wherein the communication module includes a printed circuit board (PCB) and a flexible printed circuit board (FPCB).

5. The wireless communication system of claim 1, wherein the communication module is detachably arranged in a plurality of support members formed at an internal side of the housing.

6. The wireless communication system of claim 5, wherein the plurality of support members are projected from the internal side of the housing, and the communication module is supported between the plurality of support members.

7. The wireless communication system of claim 1, wherein the housing includes a first housing that is connected to the embedded-type antenna and a second housing that is coupled with the first housing at an upper side of the first housing, and the first and second housings are formed in a cylinder shape.

8. The wireless communication system of claim 2, wherein a part of the matching unit is embedded in the base and the remaining part of the matching unit is protruding out of the base.
