Publication number: 20100188298Abstract: A challenge to be met by the present invention is to provide an antenna device that saves space while using a plate-like inverted F-shaped antenna. An external memory connector (102) is interposed between a radiating element (1011) and a ground pattern (111). Space of a circuit board (11) can thereby be saved. Further, a feeding section (1014), a first short circuit section (1013), and a second short circuit section (1012) of the plate-like inverted F-shaped antenna element (101) are aligned to each other. A layout minimizing waste thus becomes possible on the occasion of designing of a housing case (12) and the circuit board (11), thereby contributing space saving.Type: ApplicationFiled: May 31, 2007Publication date: July 29, 2010Applicant: PANASONIC CORPORATIONInventors: Yuichiro Suzuki, Hideo Nakanisi, Masashi Koshi
