ABSTRACT:
An antenna device includes an electrically insulating base section and a metallic first antenna element fixed to the base section. The first antenna element includes an adjusting section shaped like a ladder or a lattice, which is formed of rails confronting each other and connecting bars which couple a part of the rails. The structure discussed above allows the adjusting section to adjust frequency characteristics corresponding to the antenna element to desirable ones with ease, so that a basic tooling die can be commonly used and standardized antenna device is obtainable with ease.
