description PROBLEM TO BE SOLVED: To provide a broadband built-in antenna in GHz frequency bands which can be accommodated in a small and thin casing of a radio device. SOLUTION: The broadband antenna assembly built in a radio device has a configuration in which a feeding antenna is disposed and formed on an RF substrate, and the substrate is disposed in a box of the radio device casing, and a parasitic element is disposed on the inner surface of a lid of the casing so that both the elements can be capacitively coupled with each other when the box is mated to the lid. Further, one end of the parasitic element is bent to adjust the capacitance coupling. COPYRIGHT: (C)2008,JPO&INPIT
