Abstract: The present invention discloses a broadband printed antenna used in a notebook for receiving and emitting electromagnetic wave signals. The broadband printed antenna includes a substrate and a conductive layer formed on a front face of the substrate. The conductive layer includes a feeding portion for transmitting electromagnetic wave signals, a radiation portion extending leftward along an end of the feeding porting, a short portion being bent and spiral and extending rightward along the end of the feeding portion, and a ground portion extending along the short portion. The present invention includes the short portion being bent and spiral at the right side of the feeding portion for compensating a band of the notebook so that the band can reach 2.3 GHz-2.7 GHz, thereby meets various requirements of communication standards.

Abstract: A multi-band antenna is disclosed and comprises a substrate and an electro-conductive layer. The electro-conductive layer comprises: a feed-in terminal; a ground terminal; a connecting portion extended forward from the feed-in terminal; a first high frequency portion extended leftward from the connecting portion for controlling a third frequency band; a low frequency portion bent and extended leftward from the connecting portion for controlling a first frequency band and a second frequency band; and a second high frequency portion extended rightward from the connecting portion for controlling a fourth frequency band. Furthermore, the second high frequency portion is connected with the ground terminal and wider than the first high frequency portion; and harmonic oscillations are generated between the second and first high frequency portions to control a fifth frequency band. Hence, the multi-band antenna of the present invention can meet the requirement of various communication standards.

Abstract: A wireless mouse includes a mouse housing, a printed circuit board assembly assembled in the mouse housing, and an antenna mounted on a front end of the printed circuit board assembly. The front end of the printed circuit board assembly defines two fastening holes spaced from each other along a direction perpendicular to a front-to-rear direction. The antenna has a substantial long-strip radiating portion. Two opposite ends of the radiating portion are bent rearward and then downward to form a hook portion and a feed portion which are respectively hooked in the corresponding fastening holes to make the radiating portion transversely mounted over the front end of the printed circuit board assembly. The feed portion is electrically connected with a feed circuit of the printed circuit board assembly.

Abstract: A wide-band antenna mounted on a circuit board includes a ground plate, a radiating plate perpendicularly connected to two side edges of the circuit board, and a planar antenna element which includes a base plate, an extending plate, and a ground portion. One side of the base plate defines a gap with a first coupling portion being formed, and a slot adjacent to the gap with a first strip being formed therebetween. A second strip is extended perpendicularly from the first strip. The extending plate is extended outward from one end of the base plate. The ground portion is extended outward from the second strip and connected to the ground plate. The first coupling portion and the ground portion have an interspace to form a capacitive coupling therebetween. A groove is formed among the first and second strips and the ground portion to form a simulation inductance thereamong.

Abstract: Provided is a multiband printed antenna for receiving and emitting multiple electromagnetic wave signals of different bands. The multiband printed antenna includes a substrate and a conductive layer formed on a positive surface of the substrate. The conductive layer includes a grounding portion, a plurality of radiating portions controlling different bands and a single feeder point used to transmit electromagnetic wave signals. The multiband printed antenna of the present invention can separately control multiple radiating portions, which have different bands and are together formed on one same substrate, to emit the electromagnetic wave signals at one same feeder point, thereby realizing the object of the single printed antenna controlling multiple bands and greatly reducing the manufacture cost to satisfy the demand of 4G communication industry.

Abstract: Methods, systems, and apparatus, including computer program products, for exchanging information in accordance with a protocol. In one aspect, signals reporting user actions related to resources and ranking data ranking the resources based on the signals are exchanged in accordance with a protocol. The protocol defines types of user actions that can be reported by the signals, a format for specifying values for one or more of a set of predefined parameters for qualifying the user actions, a format for specifying one or more subscriber-specific parameters relating to the resources or the user actions, and a format for identifying resources to which the user actions are related using a namespace defined by the subscriber.

Abstract: Methods, systems, and apparatus, including computer program products, for ranking resources. One or more signals reporting one or more actions by the plurality of users related to a respective resource are received, where a reported action is a presentation of the respective resource, an addition of the respective resource, or a deletion of the respective resource. The reported actions include one or more short deletions of the respective resource. A respective long-addition click-through rate (LACTR) is determined for the respective resource based on a number of reported presentations of the respective resource and a difference between a number of reported additions of the respective resource and a number of short deletions of the respective resource. The plurality of resources are ranked based on the respective LACTRs for the plurality of resources. The ranking of the plurality of resources are provided.
