  • Patent number: 11165157
    Abstract: An antenna device includes a ground plate, a patch portion disposed parallel to the ground plate with a particular spacing, a plurality of short circuit portions that electrically connect the patch portion to the ground plate, and a loop portion which is a loop shaped conductor member at a particular spacing from an outer edge portion of the patch portion. The patch portion has an area which forms an electrostatic capacitance that causes parallel resonance with an inductance provided by the short circuit portions at a particular target frequency. The loop portion is formed with a perimeter length which is an integral multiple of the wavelength of radio waves at the target frequency. A feed point is disposed on the loop portion, and current is supplied to the patch portion through the loop portion.

  • Patent number: 7236803
    Abstract: A CPU of a mobile telephone can carry out both a standby operation for monitoring an incoming call addressed to the mobile telephone and an image processing operation for processing an image captured by a camera. When a camera-dedicated mode is selected, the standby operation is prohibited during an image capture operation of the camera. When the image captured by the camera is processed, negative effects of the standby operation on the process of the image captured by the camera can be avoided. In this manner, the image captured by the camera can be smoothly, appropriately processed, enhancing the operability of the mobile telephone.
