| 20100123539 | Transformer - A transformer includes a main body, at least a rubber piece and a wire-guiding groove. The main body has a primary winding partition, several secondary winding partitions and two end portions. Several leads are disposed in either end portion. The rubber piece is fitted on at least one surface of one of several primary leads. The rubber piece can strengthen the primary lead and enables the secondary wire to run closely and neatly on the surface of the rubber piece and the primary end piece. The wire-guiding groove is formed in the primary end piece. The wire-guiding groove can guide the secondary wire to keep the secondary wire running closely and neatly on the lower surface of the primary winding partition. | 05-20-2010 |

| 20100109828 | Transformer - A transformer includes a main body and a wire. The main body has several winding partitions and two end portions. Several leads are disposed in either end portion and a buffer region is formed between the right end portion and the right-most winding partition. An intermediate area is disposed between the buffer region and the right-most winding partition. One end of the wire is connected to one of the leads and the wire passes the right end portion. Before the wire goes into the buffer region, the wire is folded for several times and then is twisted and rolled for several turns to make the wire thicker. Next, the thicker wire is wound around the iron core in the buffer region for several turns and then the thicker wire passes the intermediate area and goes into the right-most winding partition. | 05-06-2010 |
| 20100123538 | Transformer - A transformer includes a main body and a secondary winding. The main body has a primary winding partition, several secondary winding partitions and two end portions. Several leads are disposed in either end portion. A wire-guiding area is formed in a sunken area in the primary winding partition and a buffer region is formed between the primary end portion and the primary winding partition. The secondary winding is wound around the core on the secondary winding partitions. One end of the wire runs from the secondary winding partitions to the wire-guiding area. Before the secondary wire goes into the buffer region, the secondary wire is folded for several times and then is twisted and rolled for several turns to make the secondary wire thicker. Then the secondary wire goes into the buffer region and then is connected to one of the primary leads. Due to the wire-guiding area and buffer region, the secondary wire would not be affected or pressed against by the primary wire. | 05-20-2010 |

| 20100123630 | MINIATURE ANTENNA - The present invention discloses a miniature antenna that has a simple structure, compact dimension and high efficiency. The miniature antenna is comprised of a dielectric element made of a dielectric material, having a first surface and a second surface opposite to the first surface, a first electrode layer being laid on the first surface, and a second electrode layer being laid on the second surface. The first electrode layer connected to a signal feeding line and the second electrode layer, connected to a ground plane, are partially overlapped to form a region that functions as a capacitor. Thereby, the miniature antenna can transmit and receive signals. The capacitance and resonant frequency of the miniature antenna can be adjusted via varying the pattern of the electrode layers, varying the thickness or permittivity of the dielectric element or via varying the size of the overlapping areas of the two electrode layers. | 05-20-2010 |
| 20110095947 | MINIATURE MULTI-FREQUENCY ANTENNA - A miniature multi-frequency antenna, comprising at least one dielectric substrate, at least one signal electrode and at least one ground electrode. The signal electrode and the ground electrode are disposed on a substrate. The signal electrode contains at least two branches and at least one branch is partially overlapped with the ground electrode. Each interlayer region between the partially overlapped electrodes forms a specific capacitance. By utilizing this interlayer capacitive effect, the resonant frequency of lower frequency band is achieved while the size of the antenna is effectively reduced. For obtaining the resonant frequency of the high frequency bands, the design concept of PIFA is applied on other branches of the signal electrode. A miniature antenna thus obtained is capable of transmitting/receiving multi-frequency signals having the benefits of easily adjusting impedance and resonant frequency. | 04-28-2011 |

| 20090179811 | ANTENNA STRUCTURE WITH FIXING UNIT - An antenna structure includes a substrate, a signal transmission unit and at least one fixing unit. The substrate is made of a dielectric material and has at least a through hole. The signal transmission unit has a transmission path and goes through the through hole. The fixing unit is made of a flexible or deformable material, and is in contact with the signal transmission unit and the inner surface of the through hole to fix the signal transmission unit on the substrate. | 07-16-2009 |
| 20090213010 | POLARIZED ANTENNA WITH REDUCED SIZE - A polarized antenna with reduced size includes a substrate, a ground electrode, a radiation electrode and a side-feeding electrode. The substrate is made of dielectric materials, and the ground electrode, the radiation electrode and the side-feeding electrode are made of electrically conductive materials. By forming a plurality of characteristics-setting elements within the radiation electrode, the polarized antenna can have the advantages of wider bandwidth and smaller size. By changing the design of characteristics-setting elements, the circular polarization characteristics of the antenna can be adjusted or a linear polarization antenna can be obtained. The present invention can be implemented to become a through-hole device or an SMD device. | 08-27-2009 |
| 20100033382 | CIRCULARLY POLARIZED ANTENNA - A circularly polarized antenna includes a substrate, a signal transmission unit, a radiation electrode and a ground electrode. The substrate is made of a dielectric material and has a through hole through both a first surface and a second surface of the substrate. The signal transmission unit goes through the through hole. The radiation electrode is disposed on the first surface of the substrate. The ground electrode is disposed on the second surface of the substrate. In addition, the radiation electrode comprises a central electrode and a plurality of peripheral electrodes. The peripheral electrodes extend from the central electrode. | 02-11-2010 |
