A composite antenna device includes a first tuning coil section 10, a second tuning coil section 20, and a common top capacity section 30. The first tuning coil section is connected to a common power feeding section 1, and functions as a part of an element for a first frequency band. The second tuning coil section 20 is connected to the common power feeding section 1, and functions as a part of an element for a frequency band that is higher than the first frequency band. The common top capacity section 30 is connected to an end section on a side opposite to a side on which the first tuning coil section and the second tuning coil section are connected to the common power feeding section and also functions as an element for a third frequency band that is lower than the first and second frequency bands. The antenna may comprise a cover having a shark fin shape. |
