摘要： There is provided a mobile wireless device capable of preventing antenna characteristics from degrading by feeding electric power at a position hardly affected by a human body such as a hand or other body part. In the mobile wireless device, a first circuit board (101) is provided on a first chassis (110) and has a ground layer; a second circuit board (105) is provided on a second chassis (120) and has a ground layer. A ground terminal of a wireless portion (104) is connected to the ground layer of the first circuit board (101) at the same voltage level and is also electrically connected through the wireless portion (104) to a matching circuit (103). The ground layer of the second circuit board (105) is electrically connected to a hinge conducting portion (106) by electrostatic capacitance coupling. The hinge conducting portion (106) is connected through a third conduction portion (107) to a board connection portion (102) and feeds power to the wireless portion through the matching circuit (103). This enables the ground layer of the first circuit board (101), the third conduction portion (107), the hinge conducting portion (106), and the ground layer of the second circuit board (105) to function as an antenna resonating at a predetermined resonant frequency.

摘要： Provided is a radio communication device which can prevent degradation of an antenna by controlling the VSWR and the current phase of antennas arranged adjacent to one another. In this device, an antenna (201) has a predetermined resonance frequency. A breaking circuit (203) is connected to the antenna (201) in parallel to a rectification circuit (205) so as to shut off the resonance frequency of the antenna (201). A termination circuit (204) electrically terminates the output side of the breaking circuit (203). An antenna (207) is arranged in the vicinity of the antenna (201) and has a resonance frequency different from a resonance frequency of the antenna (201). A breaking circuit (209) is connected to the antenna (207) in parallel to a rectification circuit (211) and shuts off the resonance frequency of the antenna (207). A termination circuit (210) terminates the output side of the breaking circuit (209).
