Abstract
A ring electrode is disposed in a ring shape opposite to a grounded electrode in a flat shape at a predetermined distance therefrom. A connection member is disposed which is made up of impedance converting portion and transmission line portion, connected in series with impedance converting portion, between the inner side of ring electrode and feeding terminal. Thus, an antenna apparatus easy to achieve impedance matching thereof by use of a connection member can be economically realized.
