20080216304METHOD OF MANUFACTURING ANTENNA MODULE BY LASER CARVING - A method of manufacturing antenna by laser carving comprising the following steps: to attach metal material such as copper, silver etc. onto the base plate by a method of conductive coating by spraying; and then to trim the metal material to complete the shape of an antenna by laser carving. Thereby, the size and shape of the antenna are not limited, and the antenna can be manufactured on a non-planar base plate, thus the height of the entire antenna module can be reduced.09-11-2008
20090100666METHOD OF INSTALLING OF ANTENNAS OF A NOTEBOOK - A method of installation of notebook antennas, the method is mainly to design to use a mode of manufacturing labels to make groups of or integrate antennas required by the notebook to make a label type antenna; then the label type antenna is stuck and fixed on an inner layer of the housing of the notebook. This method can reduce cost of manufacturing and thickness and weight of notebooks.04-23-2009
20100033400SPRAY NON-CONTACT CUTTING TYPE ANTENNA AND ITS FABRICATION METHOD - A spray non-contact cutting type antenna fabrication method is disclosed to have an antenna radiator be formed on a plastic shell by means of spray-painting a metallic spray paint on the surface of the plastic shell and then cutting the metallic coating into shape, and then to cover the plastic shell with a cover layer by means of an insert molding or spray paining technique to have the antenna radiator be enveloped in the cover layer.02-11-2010
20100164808MULTI-BAND HAC COMPATIBLE ANTENNA MODULE - A multi-band HAC compatible antenna module having a metal shield arranged around the built-in antenna for resonant coupling with the antenna to lower electromagnetic interference and to improves hearing aids compatibility characteristic. When compared with a reference antenna without metal shield, the multi-band HAC compatible antenna module shows 3 dB˜4 dB HAC improvement in GSM850 and GSM900, and 1 dB HAC improvement in DCS and PCS bands.07-01-2010
20110032170MULTI-BAND ANTENNA FOR NOTEBOOK COMPUTER - A multi-band antenna includes an insulative carrier board arranged on the top side of the display screen of a notebook computer, a main antenna which has the top metal strip thereof disposed at the top edge of the insulative carrier board and the grounding metal strip thereon arranged on the insulative carrier board, an inverted L antenna arranged on the insulative carrier board, a first capacitor, a second capacitor, an antenna feed-in terminal and/or an inductor set between the inverted L antenna and the main antenna to achieve optimal matching subject to adjustment of the capacitance values of the first and second capacitors and the inductance value and position of the inductor.02-10-2011
20110165344SURFACE ANTENNA FORMATION METHOD - A surface antenna formation method to form an antenna on the surface of an antenna carrier economically by means of spraying a conducting paint into a patterned opening of a shield being covered on the antenna carrier and then employing a laser etching technique to remove burrs from the border of the antenna thus formed on the surface of the antenna carrier after removal of the shield.07-07-2011
