Abstract: The present invention relates to an apparatus and method for inspecting the electrodes of a battery, which inspects the arrangement state of anodes and cathodes in the battery in a non-destructive manner (using X-rays). The apparatus radiates X-ray beams onto a battery in which a plurality of plate-shaped anodes and a plurality of plate-shaped cathodes are alternately stacked and inspects an arrangement state of the anodes and the cathodes. The apparatus includes a first X-ray source part for radiating a first X-ray beam onto the battery. A first detector detects the first X-ray beam having transmitted through the battery. A control unit receives an image of the battery output from the first detector, calculates a step difference between each anode and each cathode, and then inspects an arrangement state of the anode and the cathode.

Abstract: A diversity antenna is provided inside a mobile communication terminal. A common ground element formed as a conductor having predetermined length grounds the antenna. A first radiating element radiates a vertically polarized wave of a predetermined band. One end of the first radiating element is vertically connected to one end of the commnon ground element and the other end of the first radiating element is open. A second radiating element radiates a horizontally polarized wave of the predetermined band. One end of the second radiating element is vertically connected to the other end of the common ground element and the other end of the second radiating element is open. First and second feeding elements feed electric current to the radiating elements.

Abstract: A wireless LAN antenna/card which can transmit/receive RF signals in a high frequency band (e.g., 5 GHz) and a low frequency band (e.g., 2.4 GHz), includes a radiation electrode, a matching electrode and a feeding electrode. The radiation electrode has a predetermined area to define a transmission/reception frequency band of the antenna. The matching electrode has at least one open stub. The feeding electrode has a feeding point formed at an arbitrary position of the feeding electrode to receive a current, a first end connected to the radiation electrode, and a second end connected to the matching electrode. Further, the feeding point and a ground point are arbitrarily set on the feeding electrode, thus adjusting the impedance and frequency of the wireless LAN antenna.
