摘要:
A GPS antenna is provided with a reflective conductor portion. Thereby, an electromagnetic wave radiated from an antenna conductor portion in a predetermined direction can be grounded electrically, and thus radiation of the electromagnetic wave in a direction (arbitrary direction) opposite to the predetermined direction can be enhanced. As a result, the directivity of the electromagnetic wave in the arbitrary direction can be enhanced to improve the positioning accuracy.

An information processing unit is configured so that in a case where a display-rotating button 4 or 11b is operated by a user so as to select a second display mode, and where either a communication unit 5 or 13 is in an activated state and the user does not halt the action of the communication unit 5 or 13, the display mode is shifted to a mode other than the second display mode. Thereby, it is possible to urge the user to change the posture of a main body 1.

A rear surface opposite to one plane of a die pad is formed to be exposed from one plane of a sealing resin. In addition, a concave portion disposed to be parallel with at least a first side of an outermost edge of a central structure and a second side adjacent to the first side, respectively, is formed in the one plane of the sealing resin. Here, a depth of the concave portion is equal to or greater than a height of the outermost edge of the central structure.
摘要:
Electronic equipment is provided with a board 24a that includes an antenna circuit for transmitting and receiving a wireless signal and a ground pattern 24c for electrically grounding the antenna circuit, and a second casing 23 formed integrally with an antenna holding portion 23f for holding the board 24a. At least the antenna holding portion 23f in the second casing 23 is formed of a conductor. A clip 40 sandwiches the antenna holding portion 23f and the board 24a in a state where the ground pattern 24c and the antenna holding portion 23f are in contact with each other.
