1. A portable device with a proximity sensor, comprising:
- upper and lower cases;
at least one printed circuit board placed between the upper and lower cases and including a controller;
at least one first proximity sensor placed between the upper case and the at least one printed circuit board and configured to detect impedance;
at least one second proximity sensor placed between the lower case and the at least one printed circuit board and configured to detect impedance; and
at least one shielding means placed between the at least one first proximity sensor and the at least one second proximity sensor such that impedance applied through the lower case is prevented from being applied to the first proximity sensor and impedance applied through the upper case is prevented from being applied to the second proximity sensor.

Abstract
A portable device with a proximity sensor is provided. The portable device with a proximity sensor of the present invention includes a shielding plate for shielding impedance applied in a direction opposite to the direction that the proximity sensor detects the proximity such that the proximity sensor is not affected by a change in the surrounding environment and can detect the proximity at the same sensitivity at all times. Moreover, when the portable device is placed upside down on a conductive surface that causes low impedance, a proximity sensor placed adjacent to the conductive surface is deactivated to prevent malfunction.
