Passage control device for non-contacting data carriers

A passage control device for non-contacting data carriers, said passage control device having:

• an antenna unit with a front wall extending in the passage direction and facing the passageway, the height of said wall corresponding to the different wearing heights of the data carriers, and the front wall having disposed thereon at least one antenna for data transmission in the radio wave range, the front wall defining a passage space through which individuals transit by said passage control device;
• and a turnstile with an obliquely downward pointing hinge pin, a bearing that rotatably mounts said hinge pin to said antenna unit and barrier arms that extend obliquely to said hinge pin, wherein:
• the front wall of the antenna unit extends downward beyond the bearing of the turnstile;
• the turnstile is mounted to a portion of the front of the antenna unit so that the barrier arms extend into the passage space and
• the front wall of the antenna unit has a lower portion that is located below the turnstile bearing that extends obliquely rearward relative to an upper portion of the front wall that is located above the turnstile bearing.
