Title:
PATTERN ANTENNA AND RADIO COMMUNICATION EQUIPMENT USING THE SAME
Document Type and Number:
Japanese Patent JP3630622
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pattern antenna miniaturized by using a pattern antenna on the surface of a substrate or inside formed as a pattern, and to provide a radio equipment using the antenna.
SOLUTION: An inverted F-shaped antenna pattern 1 where a feeder conductive pattern 1b is connected to a feeder path 2 formed on the surface of a glass epoxy board 4 and a ground conductor pattern 1c is connected to a conductor part 3 for ground formed on the surface of the glass epoxy board 4 is formed as a driving element. Then, the feeder conductor pattern 1b is formed tapered gradually wider toward a longitudinal part pattern from a connecting part with the feeder path 2.
