Abstract
An inverted-F-shaped antenna pattern is formed as a driven element on a surface of a glass-epoxy circuit board . This antenna pattern has a feeding conductor pattern connected to a feeding transmission path formed on the surface of the circuit board and a grounding conductor pattern connected to a grounding conductor portion formed on the surface of the circuit board . The feeding conductor pattern is formed so as to have a tapered shape so that its width increases gradually from where it is connected to the feeding transmission path toward an elongate pattern of the antenna pattern
