Abstract: An antenna device is provided as a near-field communication antenna device that is configured by arranging a plurality of loop antennas. Each loop antenna includes a plurality of parallel circuits each having a capacitor and a resistance element; and a plurality of looped conductors in a shape of a loop that is divided. The divided looped conductors are connected to each other via the parallel circuits, and the plurality of looped conductors and the plurality of parallel circuits form a loop.

Abstract: A mobile terminal capable of displaying data of e-mail etc. stored in an internal memory derived from usage by each user so that the difference of the users when acquiring the data becomes clear, wherein data of received mail acquired along with processing for reception of e-mail and identification data read out from a SIM card via a SIM card interface are stored in a flash ROM associated together and wherein when displaying each received mail stored in the flash ROM on the display, the received mail associated with the identification data read out from the currently attached SIM card and the received mail associated with the other identification data are displayed differently on the display unit 105.

Abstract: In sending an e-mail to the mobile phone, the e-mail is first sent to the server apparatus. After the server apparatus identifies the sender, it sends a mail presence notice (MPN) to the mobile phone. When receiving the MPN, the mobile phone memorizes a mail ID included in the MPN in association with user identification of a SIM card. Then, the mobile phone sends a request for header data to the server apparatus based on the mail ID. When receiving the header data completely sent from the server apparatus upon the request, the mobile phone deletes the mail ID which it has memorized in association with the user identification data.
