摘要： A wireless LAN antenna comprises a dielectric substrate having a first surface and a second surface. The first surface of the dielectric substrate has a rectangular loop. A rectangular grounding copper foil is adhered within the rectangular loop. A signal feeding copper foil is further included. One end of the signal feeding copper foil is connected to the rectangular loop and the grounding copper foil, while another end of the signal feeding copper foil running across another end of the rectangular loop. Moreover, a layer of back surface copper foil is plated to the back side of the printed circuit board. This back surface copper foil covers one half of the loop on the front surface. Adjustment of the transversal dimensions of the grounding copper foil will impedance-match the antenna to the feeding structure of the antenna.

摘要： A wireless monitoring system includes a first terminal wirelessly transmitting an output associated with a monitored object to a second terminal. The first terminal includes an antenna unit including an antenna array of a number (N) of directional antennas each radiating a relatively high power density in a specific angular direction, where N≧2, and a switch unit having a number (N) of switches each coupled between a corresponding directional antenna and a transceiving unit. When the object is located in the angular direction of one directional antenna, at least one corresponding switch coupled to said one directional antenna is selectively switched to an OFF-mode and the other switches are selectively switched to an ON-mode such that the first terminal transmits the output to the second terminal through the other directional antennas, thereby ensuring relatively low radiation to the object during transmission of the first terminal.
