Document Type and Number:
Japanese Patent JP3042316
Kind Code:
B2
Abstract:
PURPOSE: To make the size of a portable radio equipment small by obtaining a more excellent antenna characteristic (gain) in the portable radio equipment to effectively use a space without losing the antenna characteristic.
CONSTITUTION: Two conductor plates 1a, 1b are placed nearly in parallel with a gap inbetween, and one-side ends of the conductor plates 1a, 1b are short- circuited by a short-circuit plate 3. On the other hand, a tuning capacitive element 4 is loaded on the other side of the short-circuiting plate 3. Then feeding point positions 8a, 8b on the conductor plates connecting to a radio equipment circuit section 5 differ from the position to which the capacitive element 4 is loaded.
