Embodiment Construction

[0019] Embodiments of the present invention are described below with reference to the drawings. figure 1 It is a figure when seeing the patch antenna which is this embodiment from the front, figure 2 yes figure 1 A-A sectional view of .

[0020] The patch antenna 1 includes a plate-shaped radiation element 2 for radiating radio waves. When viewed from the front of the patch antenna 1, the radiation element 2 is formed in a substantially circular shape. Here, the direction perpendicular to the plane (virtual plane) on which the radiation element 2 is located is the direction corresponding to the front surface of the patch antenna 1 .

[0021] Two notch portions 2 a are formed on the outer peripheral portion (outer edge portion) of the radiation element 2 , and the outer peripheral portion of the radiation element 2 is formed in a circle except for the notch portions 2 a. In this embodiment, although the notch part 2a is formed, it is not necessary to form the notch part 2a...

Abstract

According to one embodiment, an antenna mounted on a portable apparatus having a hinge structure includes: a radiating element formed in a disk shape and configured to radiate a radio wave; a power feeding element exciting the radiating element; and a ground plate including a bottom surface arranged in parallel to the radiating element and the power feeding element and a side surface configured to allow a power feeding path feeding electric power to the power feeding element to pass in an area different from an area opposed to the hinge structure.

Description

technical field [0001] The present invention relates to a planar antenna and a portable device used in a portable RFID (Radio Frequency Identification, radio frequency identification) reader and the like. Background technique [0002] Patent Document 1 describes a configuration in which a feeder (coaxial connector) is provided on the rear surface of the antenna. In addition, Patent Document 2 describes a configuration in which a feeder is provided on a side surface of the antenna. [0003] When an antenna is intended to be mounted on a portable device having a hinge structure, if the feeder of the antenna is located at a position that interferes with the hinge structure of the portable device, the size of the portable device will increase. In order to miniaturize the portable device, it is necessary to avoid interference between the power feeder and the hinge structure. [0004] [Patent Document] [0005] Patent Document 1: Japanese Patent Laid-Open No. 2004-48364 [000...
