摘要： An antenna device 1 has an antenna unit 2 which includes an antenna core member 5 including a soft magnetic member 51 having conductivity and a conductor member 6 which is attached to the antenna core member 5. At least part of the antenna core member 5 (for example, a core sheet 50A) is a sensor electrode which is able to detect an object. The sensor electrode is used as a sensor electrode such as a capacitance-operated sensor electrode. Thus, it is possible to provide an antenna device and a door handgrip apparatus having an antenna unit including an antenna core member which is shared for an antenna function and a sensor function.

摘要： A microstrip antenna device for circularly polarized waves includes a dielectric sheet member, one surface of which has a radiating conductor sheet member while the opposite surface has a ground conductor sheet member. Denoting a point where a segment of a line passing through a geometrical center o, o of the radiating conductor sheet member intersects with the substantial periphery of the radiating conductor sheet member by a and denoting a point where the segment intersects with the substantial periphery of the ground conductor sheet member by b, the ratio of the length between the points o and b to the length between the points o and a should be at least equal to 1.5. Where rectangular radiating and ground conductor sheet members are used, a good circular polarization is achieved without any disturbance in the radiating pattern when the diagonal ratio of the respective members is equal to or greater than 1.5.
