发明名称 CELLULAR PHONE EQUIPMENT
摘要 PROBLEM TO BE SOLVED: To achieve cellular phone equipment for performing radio transmission smoothly with high sensitivity and reducing the influence on a human body regarding signals at two different frequency band signals corresponding to mutually different communication services, regardless of the presence or absence of the difference in a communication protocol. SOLUTION: A first antenna 11, operating at a first frequency band corresponding to a first communication service, is arranged on an enclosure upper surface 10a, and projects upward in a fixed or expansion and contraction accommodation structure. Conversely, to cope with the second communication service having a communication protocol that differs from that of the first communication service, a second antenna 16 operating at a second frequency band, that differs from the first frequency band is arranged in an enclosure bottom surface 10b located at the lower portion of an operation section 14, at a position that is not covered by operator's hands for retaining the cellular phone equipment 10, and at a position which would be separated maximally from the first antenna 11.
