The entire disclosure of Japanese Patent Application No. 2008-021983 filed on Jan. 31, 2008, including specification, claims, drawings and abstract is incorporated herein by reference in its entirety.
BACKGROUND
1. Field of the Invention
One aspect of the present invention relates to a thin-sized mobile apparatus, and more particularly, to arrangement of an antenna and the like.
2. Description of the Related Art
As a type of mobile phone, there is a thin-sized mobile phone. Since the mobile phone is than, the mobile phone may be used closer to a human body. In this case, it is necessary to examine the optimal arrangement of an antenna, in consideration of the effect of the human body on performance of the antenna.
It is well known that a human body deteriorates performance of an antenna. There is a mobile wireless terminal studied in consideration of such an effect (see JPA-2005-354501 (page 1, page 5, FIG. 1, and FIG. 2, for instance). The mobile wireless terminal is formed in a chest pocket type and has a flat side A and an uneven side B, and the antenna is disposed on the side B. A user puts the mobile wireless terminal in the chest pocket unconsciously to have the flat side A facing a user's body, and thus an antenna on the side B is away from the user's body, thereby securing performance of the antenna.
A non-contact type IC card such as an employee identification card has been well known (see JP-A-11-328348 (page 1 and FIG. 1)). Such an IC card has a printed face for identifying an employee with eyes and has an antenna for a non-contact IC therein.
In JP-A-2005-354501, a configuration for putting the mobile wireless terminal in a chest pocket is described, but there is no description of arrangement of an antenna in a case of using the mobile wireless terminal with a neck strap hanging on a neck. In JP-A-11-328348, there is no description of antenna communication in a state where an IC card hung on a neck with a neck strap close to a human body, and a user performs communication for non-contact IC generally in a state where the IC card is put close to an external reader/writer device. The IC card does not have a function of a mobile phone, and there is no description about a phone communicating antenna.
