To provide a radio communication card terminal wherein a projected part of the antenna is reduced even when the antenna is moved and the mechanical strength of the antenna can be enhanced.
A plate-shaped casing 1 contains a circuit board therein and a connector 11 to the circuit board is fitted to a connector fitting part 6 of the casing 1. A notch-shaped rotary plate container part 7 is formed on a rear side of the casing 1, a rotary plate 13 with a chip antenna 14 mounted to both ends thereof is turnably arranged at the rotary plate container part 7 to configure an antenna system 12. Thus, the rotary plate 13 is properly positioned between a horizontal planar position and a vertical rising position to form a desired radiation pattern. Further, the antenna is less caught by clothing or the like of an operator in comparison with a rod antenna element so as to enhance the workability and increase the mechanical strength of the rotary plate 13.
