A variable phase shifter is provided. In the variable phase shifter, a fixed substrate, which is a dielectric substrate, is fixedly mounted in a housing and has at least one arc-shaped microstrip line on one surface thereof. A rotation substrate, which is a dielectric substrate, is rotatably mounted in the housing, in contact with the other surface of the fixed substrate and has a slot line on the contact surface thereof. Microstrip-slot line coupling takes place between the microstrip line and the slot line even during rotation. Both ends of the microstrip line are connected to an output port of the variable phase shifter and the slot line is electrically connected to an input port of the variable phase shifter, for receiving an input signal.

The present invention is provided to report a loss of a terminal in a wireless communication system. A method of detecting the loss of the terminal includes comparing information elements that change depending on geographical movement of a primary terminal and a secondary terminal when a time for detecting the loss arrives. The loss of the secondary terminal is detected based on the comparison result of the information elements that change depending on the geographical movement of the terminals. The loss of the secondary terminal is reported to the primary terminal.

Provided is an apparatus and method for transmitting digital multimedia broadcasting (DMB) program information in a DMB receiving terminal. If a user desires to recommend a broadcasting program to another user, the DMB receiving terminal extracts broadcasting information of the selected broadcasting program, searches for broadcasting program information corresponding to the extracted broadcasting information from Electronic Program Guide (EPG) data, generates Caller Information Sending Service (CISS) information including the found broadcasting program information, and transmits a call signal including the CISS information to a specific recipient so that the CISS information is stored as call-record information in a DMB receiving terminal of the specific recipient. Then, the recipient can check the broadcasting program using the CISS information. Accordingly, broadcasting program information of DMB can be easily exchanged between users.

A micro-strip transmission line capable of reducing far-end crosstalk is provided. The micro-strip transmission line having a serpentine shape is capable of reducing the far-end crosstalk of the transmission line by increasing capacitive coupling between neighboring transmission lines by allowing parallel micro-strip transmission lines to have serpentine shapes. In the structure of the micro-strip transmission line having the serpentine shape, it is possible to reduce the far-end crosstalk of the transmission line by increasing capacitive coupling between neighboring transmission lines by allowing parallel micro-strip transmission lines to have serpentine shapes.

A vibration motor is disclosed. In accordance with an embodiment of the present invention, the vibration motor includes a base, a vibrator, which reciprocates in the base, a protruding part, which is formed on at least one of the base and the vibrator, and an elastic body, which is interposed between the base and the vibrator and has a through-part formed therein and in which the protruding part is inserted into the through-part and the elastic body is coupled to the base or the vibrator by caulking or bending the protruding part which is protruded through the through-part. Thus, the vibration motor can have a uniform resonant frequency characteristic since a spring is coupled by way of caulking or bending.
