PROBLEM TO BE SOLVED: To house a GPS(global positioning system) antenna part and an antenna part for telephone in a small-sized antenna case. SOLUTION: A GPS antenna part 4 is housed in a GPS antenna housing part 3b formed on an elliptical metal base 3. An antenna part 5 for telephone consists of a linear element part and a circular crown part which is provided in the tip of the element part and is bent downward so as to be an umbrella shape. Because the crown part is bent downward, capacity produced between the metal base 3 operating as a ground plane and the crown part becomes large enough to make the diameter of the crown part small. Thus, it is possible to make the shape of the antenna part 5 for telephone small and to house the part 5 in an antenna case consisting of a cover 2 and the metal base 3. |
