PURPOSE:To reduce connecting loss without reducing the gain of an antenna and to simplify the constitution of an antenna system by mounting a part of radio equipment on a supporting member of a primary radiator formed like a plate and arranging transmission lines inside the supporting member. CONSTITUTION:The primary radiator 33 is supported on the front end part 32a of the plate-like supporting member 32 by inserting its body part 33b into the inside of a connector block 34. The radio equipment 47 of a transmission/reception part is planely mounted on a supporting body inside the front end of the member 32 and transmission lines 48a, 48b, 49a-49c connected to the equipment 47 are arranged in the member 32. The lines 48a, 48b are arranged on a flexible printed board as I/O lines and connected to the radiator 33 through a connecting terminal 50 and the lines 40a-49c are arranged on the flexible printed board as transmission/reception and power supply lines, and connected to a room terminal through a back end part of the member 32. |
