Abstract: A mobile device and a method thereof are provided. The mobile device includes a display configured to display an image; a metal bezel surrounding an outer perimeter of the display; a temperature sensor configured to measure a temperature of an object via the metal bezel; and a controller configured to control the display to output the temperature measured using the temperature sensor.

Abstract: An optically open stacked type subminiature optical device according to the present invention has an independent aperture stop structure to enable designing of a stable small optical device having an optical open cover structure, thus improving optical performance. Further, the optically open stacked type subminiature optical device of the present invention is configured in that the aperture stop structure is assembled with another structure into a stacked structure to establish a stable assembly together with the cover structure, thereby allowing for ease of assembly and improving productivity.

Abstract: Disclosed herein is a surface mount antenna apparatus applied to a wireless terminal. The antenna apparatus includes a printed circuit board having a ground pattern, a land structure, and an antenna. The land structure includes a non-grounded area having no ground electrode, first and second land pads formed on opposite ends of the non-grounded area to be connected to ground electrodes, and an input pad formed between the first and second land pads and separated from them. The input pad is spaced apart from the first land pad by a preset interval. The antenna includes first and second ground electrodes formed on the lower surface of a dielectric block to be connected to the first and second land pads, a feeding electrode connected to the input pad, and a radiation electrode formed on some of the side surfaces and the upper surface of the dielectric block. The radiation electrode is connected to at least one of the first and second ground electrodes and the feeding electrode.

Abstract: A dielectric filter stopping a frequency signal at a lower frequency band than a pass band as a reference band with a higher attenuation ratio to perform adjustment of the attenuation ratio even the lower frequency area. The dielectric filter comprises a predetermined conductive pattern on the front surface on a dielectric block in which a plurality of resonant holes are provided, the dielectric block including back and side surfaces covered with a conductive material, each resonant hole being covered with the conductive material in the internal surface, the predetermined conductive pattern being separated at a predetermined distance from the end portions of the resonant holes, whereby the predetermined conductive pattern forms a coupling capacitance between the adjacent resonators and a cross coupling capacitance between the resonators not adjacent to control an electromagnetic coupling over the whole dielectric filter.
