Abstract

Disclosed is a smart tracker for communicating with a parent terminal by Bluetooth communication and communicating with the parent terminal by ultra-wideband communication during positioning. The disclosed smart tracker comprises: a first housing; a second housing coupled to the first housing to form an inner space; a circuit board arranged in the inner space formed by the first housing and the second housing; a buzzer mounted on the lower surface of the circuit board; a battery mounted on a surface of the circuit board; a first antenna arranged on the upper surface of the circuit board and spaced from the areas on which the buzzer and the battery are mounted; and a second antenna arranged on the upper surface of the circuit board and spaced from the areas on which the buzzer and the battery are mounted and from the first antenna.

First claim

The invention claimed is:

1. A smart tracker comprising:
a first housing;
a second housing combined with the first housing to form an inner space;
a circuit board disposed in the inner space formed by the first housing and the second housing;
a buzzer mounted on a lower surface of the circuit board;
a battery mounted on a lower surface of the circuit board;
a first antenna disposed on an upper surface of the circuit board and spaced apart from an area on which the buzzer and the battery are mounted; and
a second antenna disposed on the upper surface of the circuit board and spaced apart from the area on which the buzzer and the battery are mounted and the first antenna,
wherein the buzzer includes a stepped part formed on one surface facing the lower surface of the circuit board,
wherein the lower surface of the circuit board and the stepped part of the buzzer form an accommodation space, and at least a part of the battery is accommodated in the accommodation space, and
wherein the antenna and the second antenna are mounted on the positions spaced apart from an area overlapping the buzzer and the battery.

2. The smart tracker of claim 1 , wherein the circuit board includes a first corner and a second corner opposite to the first corner,
wherein the first antenna is disposed adjacent to the first corner on the upper surface of the circuit board, and
wherein the second antenna is disposed adjacent to the second corner on the upper surface of the circuit board.

3. The smart tracker of claim 1 , wherein the circuit board includes a first side, a second side facing the first side, a third side connected to one end part of the first side and one end part of the second side, and a fourth side connected to the other end part of the first side and the other end part of the second side and facing the third side, and
wherein the first antenna is disposed adjacent to the first side and the second side, and the second antenna is disposed adjacent to the third side and the fourth side.

4. The smart tracker of claim 1 , further comprising:
a first signal processing element disposed on the upper surface of the circuit board to process a first signal received from the first antenna, and spaced apart from the area on which the buzzer and the battery are mounted, the first antenna, and the second antenna; and
a second signal processing element disposed on the upper surface of the circuit board to process a second signal received from the second antenna, and spaced apart from the area on which the buzzer and the battery are mounted, the first antenna, the second antenna, and the first signal processing element.

5. The smart tracker of claim 1 , further comprising a control element mounted on the circuit board,
wherein the control element is configured to communicate with a parent terminal through the first antenna, and
wherein the control element is configured to activate the second antenna in response to a positioning request from the parent terminal, having been received through the first antenna, and deactivate the second antenna in response to a positioning termination request from the parent terminal.

6. The smart tracker of claim 1 , wherein the first antenna is configured to resonate with a frequency of a Bluetooth communication band, and the second antenna is configured to resonate with a frequency of a UWB communication band.
