Title:
PORTABLE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2010/073723
Kind Code:
A1
Abstract:
Disclosed is a portable terminal that can improve antenna characteristics regardless of the opened or closed state of a case. A portable terminal (1) comprises a first case (2) and a second case (3), a opening/closing sensor (45), which is able to detect an open state and a closed state, a circuit (32), comprising a ground (35), a power supply (36), and a signal processor (37), a first conductor (31), which is disposed in the first case (2) and connected to the ground (35), and a second conductor (400), which is disposed in the second case (3) and connected to the power supply (36), wherein the second conductor (400) is configured having a first part (41) and second part (42), which are adjacently disposed in the alignment direction of the first conductor (31) and second conductor (400) in the open state, and is further equipped with a controller (44) which, when the closed state is detected, provides high-frequency shielding of the second part (42) from the first part (41) and, when the open state is detected, provides high-frequency coupling between the first part (41) and second part (42).
