[0123] Furthermore, when operating the second sensor 162, sensing noise in the second sensor 162 caused by changes in the dielectric constant due to contact with the aerosol generating device by the user's body or other means can be prevented. For example, the ground plane 230 connected to the second sensor 162 can prevent noise from the outside of the upper housing 200 from being generated near the second sensor 162, thereby improving accuracy when sensing information about the remaining amount of liquid in the rod or the barrel.

[0124] Windows 216 and 226 may be formed at positions corresponding to the first chamber C1 and may extend vertically along the height of the first chamber C1.

An aerosol generating apparatus, the aerosol generating apparatus comprising: The main body includes an insertion space; A sensor, which is mounted on the body and configured to detect the electromagnetic properties of the surrounding environment; An upper housing, detachably connected to the body, and including an insertion hole corresponding to the opening of the insertion space; as well as A ground plane is attached to the upper housing and extends along the outer periphery of the upper housing, and is configured to electrically ground the sensor.

2. The aerosol generating apparatus according to claim 1, further comprising: A second terminal is connected to the sensor and exposed from the body; as well as The third terminal is connected to the ground plane and is mounted on the upper housing to be exposed inside the upper housing, thereby contacting the second terminal when the upper housing is connected to the body.

3. The aerosol generating apparatus according to claim 2, wherein, The second terminal is exposed upward from the upper part of the body, and The third terminal is exposed downward from the upper wall of the upper housing.

4. The aerosol generating apparatus according to claim 2, wherein, When the upper housing separates from the main body, the third terminal separates from the second terminal.

5. The aerosol generating apparatus according to claim 2, wherein, The third terminal is a clip-on pin or a spring pin.

6. The aerosol generating apparatus according to claim 1, wherein, The upper housing includes: Upper wall, the upper wall covering the upper end of the main body; and A transverse wall that covers the transverse surface of the outer periphery of the body. The grounding plate is installed at the transverse wall and extends along the outer periphery of the transverse wall.

7. The aerosol generating apparatus according to claim 6, wherein, The upper housing includes: Inner shell; and An outer shell, the outer shell being connected to surround the outer side of the inner shell. The grounding plate is disposed between the inner shell and the outer shell.

8. The aerosol generating apparatus according to claim 7, wherein, The inner shell includes: The first rib supports the upper end of the grounding plate; and The second rib supports the lower end of the grounding plate.

9. The aerosol generating apparatus according to claim 7, further comprising: A second terminal is connected to the sensor and exposed from the body; Terminal hole, the terminal hole being formed on the upper wall of the inner housing; The upper end of the ground plane has a connecting portion that is bent inward to be disposed in the terminal hole; as well as The third terminal is mounted on the connection portion and exposed inside the inner housing to contact the second terminal.

10. The aerosol generating apparatus according to claim 9, further comprising: A locking protrusion protrudes from the inner housing at the terminal hole and is configured to contact the connection portion when the third terminal contacts the second terminal to restrict vertical movement of the connection portion.

11. The aerosol generating apparatus according to claim 1, wherein, The ground plane is a flexible printed circuit board (FPCB).

12. The aerosol generating apparatus according to claim 1, wherein, The upper housing includes a cap configured to cover or expose the insertion hole.

13. The aerosol generating apparatus according to claim 1, wherein, The sensor is positioned adjacent to the insertion space.
