Wireless terminal device

摘要

A first conduction part (12) coated with a conductive paint is formed on a back housing (1CAR) to be attached to one housing of a portable telephone unit at a position near a hinge mechanism (9) which connects the one housing to the other housing of the portable telephone unit. A GPS antenna is disposed on the hinge mechanism (9) side inside the other housing. The first conduction part (12) is in contact with a conductive connection terminal (21). A condenser element (22C) and a coil element (22L) are connected in parallel between the connection terminal (21) and a reference potential line (10G) of a first circuit board (10) disposed inside the aforementioned one housing.

主权项

1. A wireless terminal device comprising:
circuit boards disposed inside a plurality of housings, respectively; a connecting section connecting the plurality of housings; conductive sections located on the inner side of the respective housings at the connecting section, and transmitting high-frequency current; a first antenna for a first frequency band, the first antenna disposed on the opposite side of the connecting section on an circuit board; a second antenna for a second frequency band, the second antenna disposed on the connecting section side on the circuit board; a connecting terminal that is disposed on the connecting section side and that comes in touch with the conductive section; a first filter that is located between the connecting terminal and the reference potential line of the circuit boards and that interferes with a passage of the second frequency band, the first filter comprising at least a capacitor element that is connected in series between the connecting terminal and the reference potential line.
