Abstract: The present invention applies management frame defined in IEEE 802.11 standard to a wireless distribution system (WDS) mode by adding an information element (IE) into the management frame, which enables any access point (AP) in WDS to maintain IE based on its own setting and state, then send IE via the management frame for providing state of the AP under WDS mode, determine whether a physical link (i.e., a wireless link between APs) should be established therewith based on received IE, and maintain the established physical link through the wireless management frame in a real time manner. Thus, the existence and necessity of the physical link between different APs in WDS can be determined correctly.

Abstract: The present invention provides a communication device and a digital encoding method thereof. The communication device comprises a first and a second emitting devices respectively communicating at a first and a second communication channels. Each emitting device emits the same piece of data through continually emitting the same signal section for six times. The signal section is encoded in five bits. A receiving device alternately jumps between the first and second communication channels to receive signal sections emitted by the first and second emitting devices. The time of the receiving device at each communication channel comprises a phase lock time and a reception time of a whole signal section. The present invention has the advantages of having a very good quality of data transmission, reducing the cost, saving installation space, and facilitating the operation.

Abstract: The present invention discloses an antenna array installed on a printed circuit board, which comprises two antenna units, each being a microstrip directly installed on two symmetric ends of a T-shape microstrip on a printed circuit board and an asymmetric end of the T-shape microstrip circuit being a feeding end feeding signals simultaneously to the two antenna units. A grounding metal surface is fabricated on the other side of the printed circuit board at a position other than the antenna unit, and keeps a specific distance from at least one corresponding edge of the antenna unit. Since the antenna units are symmetric in shape and have the same feeding end, the radiation direction thereof is shifted towards the two symmetric edges to broaden the range of the use of two symmetric edges.

The first substrate module includes a parasitic element, and a radiator disposed below the parasitic element. The second substrate module is stacked below the first substrate module, and is provided with first and second slots. The third substrate module is stacked below the second substrate module, and includes first and second feed lines. When the antenna operates in a transmit mode, signals fed to the first and second feed lines are electromagnetically coupled to the first and second slots, then to the radiator, and finally to the parasitic element, and the parasitic element transmits an electromagnetic wave. When the antenna operates in a receive mode, the parasitic element receives an electromagnetic wave, and the electromagnetic wave is electromagnetically coupled to the radiator, then to the first and second slots, and finally to the first and second feed lines.

Abstract: A radome having multi-size metal patterns and a radar device using the radome are provided. The radome includes alternately-arranged dielectric substrates and metal layers. Each metal layer includes metal frames and metal patterns wherein the metal patterns are electrically insulated from each other. A gap width corresponding to one metal pattern of one metal layer is a width of a gap defined between the metal pattern and a nearest metal frame to the metal pattern. The gap widths corresponding to the metal patterns are increasing, decreasing and further increasing in sequence along a radial direction extending from a center to an outer edge of the metal layer. The outmost layers at both sides of the radome are metal layers. The metal layers have substantially identical layout.
