Abstract
A multi-band antenna includes two conductive wirings and unit circuits cascaded along the conductive wirings. Each unit circuit includes a communication unit, a first capacitor and a second inductor. The communication unit connects between the conductive wirings through a first inductor and a second capacitor connected in series with the first inductor. The first capacitor and the second inductor are inserted in at least one of the conductive wirings. The second inductor is connected in parallel with the first capacitor. Alternatively, the unit circuit includes a communication unit connecting between the conductive wirings through a first inductor, and a first capacitor inserted in at least one of the conductive wirings. The first inductor, the first capacitor, a third capacitor disposed between the conductive wirings, and a third inductor disposed on at least one of the conductive wirings satisfy a relationship expressed by the expression 2.
