20090002239 | MICRO-STRIP ANTENNA WITH L-SHAPED BAND-STOP FILTER - A micro-strip antenna includes an L-shaped coupler, a set of micro-strip antennas, and an L-shaped band-stop filter. The set of micro-strip antennas includes at least one rectangular micro-strip antenna unit and a micro-strip line. The rectangular micro-strip antenna unit is coupled to the micro-strip line. The micro-strip line is coupled to the first end of the coupler. The band-stop filter is disposed along a corner of the rectangular micro-strip antenna unit, and is disposed between the antenna unit and the coupler without being physically connected to the antenna unit and the coupler. The width, length, and position of the L-shaped band-stop filter can be determined for the specific band-stop frequency and to optimize its coupling extent with the L-shaped coupler. | 01-01-2009 |
20090303693 | Wireless Power Transmitting Apparatus - A wireless power transmitting apparatus for remotely transmitting energy is implemented with a closed metal housing and a plurality of conductive plates disposed within the closed metal housing. With the aid of a high impedance between the closed metal housing and the conductive plates, a surface having the high impedance is formed on both the closed metal housing and the conductive plates for constraining electromagnetic power within the closed metal housing from dissipating and being consumed. The wireless power transmitting apparatus is not merely able to effectively and uniformly restrict electromagnetic field energy to the closed metal housing with the aid of the high impedance, but is also be able to raise a power transmitting efficiency between a power emitting device and a power receiving device. | 12-10-2009 |
20100238084 | Dual-band Planar Micro-Strip Antenna - To meet the requirements including dual-band, a high gain, and a broadside radiation formation, a dual band planar micro-strip antenna utilizing antenna array is provided. One array element includes a rectangle-shaped micro-strip antenna and an arrow-shaped micro-strip antenna. A first resonant frequency is determined by a length of the rectangle-shaped micro-strip antenna. Slots are dug for satisfying a second resonance frequency. Curved surfaces of the arrow-shaped micro-strip antenna designed according to an ellipse equation so that a frequency resonance is reached under both the first resonant frequency and a second resonant frequency, and a broadside radiation formation is thus generated. A T-shaped jointer distributes power between antenna elements according to the output impedances of the antenna elements. An L-shaped band-stop filter located on the T-shaped jointer is utilized to suppress frequency resonance resulted from multiples of the first resonant frequency. | 09-23-2010 |
