摘要： A flat antenna with a simplified feeder point is provided. The flat antenna consists of a round patch antenna section, a dielectric material, a grounded conductive plate. The patch antenna section is arranged so as to confront the grounded conductive plate via the dielectric material. The center conductor of a coaxial cable is inserted into the opening formed in the grounded conductive plate and further penetrates the dielectric material of a thickness of t. The center conductor is electrically connected with the feeder point P of the patch antenna section. The outer conductor of the coaxial cable is connected to the grounded conductive plate. The center conductor has the inductive impedance L added by the penetration length of the dielectric material. Improved matching characteristics can be provided by setting the resonance frequency of the patch antenna section to a higher frequency than receive frequencies and by adding a capacitive impedance to the impedance of the feeder point.

摘要： A display-integrated tablet device capable of improving luminance of an image displayed while carrying out coordinate detection plural times during a one-image-plane display period. X-coordinate detection is carried out in a manner to take, in an X-coordinate detection section, a voltage obtained by feeding each of second gate electrodes with a pulse generated in a pen-pulse generation circuit. Y-coordinate detection is carried out by inputting a voltage obtained by outputting of a pulse for scanning Y-electrodes (lines) from a stylus pen to a Y-coordinate peak detection circuit. After coordinate detection is thus executed, only Y-electrodes in a predetermined range about a Y-coordinate previously detected are scanned in a Y-coordinate detection period provided after each of block display periods defined by dividing an image display period.
