PROBLEM TO BE SOLVED: To provide an in-building radio wave repeater requiring no power source that attains radio communication, without being disturbed by a shield and obtains a maximum gain in the case of a plurality of base stations even when at least one room in two rooms going to make mutual communication is surrounded by a radio wave shield, otherwise, causing disabled communication due to interruption of radio communication radio waves. SOLUTION: In the in-building radio wave repeater requiring no power source that is provided with a base station side antenna section 4 making communication with a plurality of base stations, a weak electric field side antenna section 5 making communication with a weak electric field side, and a cable 6 interconnecting the base station side antenna section 4 and the weak electric field side antenna section 5, the base station side antenna section 4 is provided with a plurality of antenna elements 41a-41d. The base station side antenna section 4 is provided with circuits 42a-42d to be matched with the impedance of the weak electric field side antenna section 5. |
