Abstract: A radiation patch having a shape of linearly-tapered rectangle for a planar inverted F antenna is disclosed. The planar inverted F antenna having a radiation patch includes: a ground unit for grounding a radiation patch; a short unit for shorting the radiation patch; a feeding unit for supplying an electric power to the radiation patch; and a radiation patch for radiating electric power from the feeding unit, wherein the radiation patch having a shape of linearly tapered rectangle and a length and width of tapered sides of radiation patch is determined according to a resonate frequency. As mentioned above, the present invention can be easier to be designed and provide wider bandwidth by providing a linearly tapered rectangle shape of radiation patch in a planar inverted F antenna.

Abstract: PURPOSE: An apparatus and method for monitoring and tracking an electromagnetic field in real time are provided to construct a safe electromagnetic environment by tracking a dangerous discharge source. CONSTITUTION: A receiving sensor unit(102) receives a broadband electromagnetic signal. A frequency scanning unit(104) extracts a waveform for a service according to each frequency band. A monitor unit(108) calculates a peak exposure index and monitors information about a dangerous electromagnetic field discharge source and a service signal with the maximum value. A tracking unit(110) searches the location of a signal source. A remote transmitting unit(112) performs a remote transmission. A remote monitor unit(114) feeds back the information about the dangerous electromagnetic field discharge source to the tracking unit.

Abstract: A noble method for coating the surface of a mica powder with silver to improve corrosion resistance and electromagnetic shielding efficiency of the mica powder is provided. A method for coating a mica powder with silver comprises the steps of: degreasing and etching a mica powder; sensitizing the degreased and etched mica powder; and adding the sensitized mica powder into a solution comprising a silver compound, a complex and a stabilizer, and injecting a reductant into the mixed solution within 5 minutes, and coating the mica powder with the solution. The mica powder can be replaced with a plastic powder or a ceramic powder. The complex is ammonia water. The stabilizer is at least one selected from the group consisting of ammonium bicarbonate and ammonium carbonate. The reductant is at least one selected from the group consisting of hydrazine monohydrate, formalin, glucose, ascorbic acid, sugar-alcohol, and borohydride.
