An antenna and a manufacturing method therefor are disclosed, in which the sensitivity characteristic of the dual band antenna utilizing a plurality of frequency bands is improved, and at the same time, the antenna can be miniaturized. A first cylindrical body 110 around which a primary coil 100 is spirally wound is inserted into a second cylindrical body 220 around which a secondary coil is wound. A projected portion of the primary coil 100 is electrically connected to the secondary coil 200, thereby forming a dual band antenna 300.
摘要:
In a smart energy management system linked with home network devices respectively installed in a plurality of households to manage the use of energy for each household, a location detecting unit detects location information or entry/exit information of a household member through recognition of an RFID tag carried by the household member connected with an RFID receiving device. An energy recording unit receives energy use details of the household, inputted from the home network device, and records the received energy use details together with the location information or entry/exit information of the household member. A pattern analysis unit analyzes an energy use pattern for the energy use details. An energy management unit provides the energy use details through the home network device as a result obtained by comparing the energy use detailed for each household or so that the household member recognizes the energy use pattern.

A chip antenna for use in Bluetooth, in a wireless LAN and in a mobile communication terminal includes an antenna body has an antenna-forming conductor line located therein, and a feeding terminal formed on one end thereof. A PCB (Printed Circuit Board) includes a conductor pattern located thereon so as to be connected to the conductor line of the antenna body. Further, the PCB has a feeding line located on one side of the conductor pattern so as to be connected to the feeding terminal of the antenna body. Still further, the PCB has a fixing terminal located on another side of the conductor pattern so as to be connected to the conductor pattern. Thus, a part of an antenna conductor line is located on the surface of a circuit board, and an antenna body with an antenna formed therein can be installed on the circuit board in a simple manner.
