Abstract
The present invention provides a communication apparatus and a communication method that can easily indicate the position of the antenna incorporated in the communication apparatus to a user and can align the antenna of the communication apparatus with the antenna of an external device. A portable device (1) includes a loop antenna (11) for performing near-field communication, a display unit (12) provided on a side of the portable device (1) opposite the orientation of the loop antenna (11), and an antenna position information storing unit (142) that stores antenna position information representing the position of the loop antenna (11) in the portable device (1). The display device (12) displays the position of the loop antenna (11) on the basis of the antenna position information stored in the antenna position information storing unit (142).

10. A communication apparatus that communicates with a server connected via a network and also communicates with an external device provided with a Radio Frequency Identification (RFID) tag by using near-field communication, the communication apparatus comprising:
-
a loop antenna that outputs a polling signal by near-field communication to the RFID tag provided in the external device and receives a polling response by near-field communication from the RFID tag provided in the external device that has received the polling signal; a display unit provided on a side of the communication apparatus opposite an orientation in which the loop antenna transmits the polling signal and receives the polling response; a communication apparatus identification information storing unit that stores communication apparatus identification information for identifying the communication apparatus; a position information acquisition unit that transmits the communication apparatus identification information stored in the communication apparatus identification information storing unit to the server and acquires, from the server, antenna position information that represents a position of the loop antenna in the communication apparatus and that corresponds to the communication apparatus identification information; and a position information storing unit that stores the acquired antenna position information, wherein the display device displays a guide pattern indicating the position of the loop antenna on the basis of the antenna position information which is stored in the position information storing unit, within a period in which the loop antenna outputs the polling signal to the external device. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A communication method in a communication apparatus that communicates with a server connected via a network and also communicates with an external device provided with a Radio Frequency Identification (RFID) tag by using near-field communication, the communication method comprising the steps of:
-
outputting a polling signal to the RFID tag provided in the external device from a loop antenna that is provided in the communication apparatus and performs near-field communication; receiving with the loop antenna a polling response transmitted from the RFID provided in the external device that has received the polling signal; transmitting communication apparatus identification information for identifying the communication apparatus to the server; acquiring, from the server, antenna position information that represents a position of the loop antenna in the communication apparatus and that corresponds to the communication apparatus identification information; and displaying a guide pattern indicating the position of the loop antenna on the basis of the antenna position information within a period in which the loop antenna outputs the polling signal to the external device, on a display unit provided on a side of the communication apparatus opposite an orientation in which the loop antenna transmits the polling signal and receives the polling response.
