Further, in the building B, Wx indicates a second-floor wall, Wy indicates a second-floor floor, and Wz indicates a first-floor floor, which respectively form the partition W. On the other hand, C indicates an automobile existing away from the building B.

【0011】 通信システム1は壁Wx、床Wy、床Wzにより仕切られた交信エリアAa、 Ab、Ac、Adに、それぞれ中継アンテナ4a、4b、4c、4dを配設し、 各中継アンテナ4a、4b、4c、4dは接続配線5iにより接続することによ り、中継器2i…を構成する。即ち、図2に示すように、例えば、壁Wxに穴H を明け、この穴Hに同軸ケーブルを用いた接続配線5iを通すとともに、接続配 線5iを各中継アンテナ4a…(交信エリアAa…)に対応して分岐させ、接続 配線5iの各先端に各中継アンテナ4a…を接続して構成する。In the communication system 1, relay antennas 4a, 4b, 4c and 4d are respectively arranged in communication areas Aa, Ab, Ac and Ad partitioned by a wall Wx, a floor Wy and a floor Wz, and each relay antenna 4a, By connecting 4b, 4c, and 4d with the connection wiring 5i, the repeater 2i ...

Is connected to each tip of the connection wiring 5i.

【0012】 また、自動車Cの仕切部、即ち、ルーフWwの両面側にもそれぞれ中継アンテ ナ4e、4fを配設し、各中継アンテナ4eと4fも上記同様に接続配線5jに より接続することにより、中継器2jを構成する。よって、自動車Cの室内は交 信エリアAeとなる。Further, relay antennas 4e and 4f are also provided on the partition of the automobile C, that is, on both sides of the roof Ww, and the relay antennas 4e and 4f are also connected by the connection wiring 5j in the same manner as above.
