Abstract
An antenna includes a base, a first radiating element, and second radiating element. The first radiating element is open at a first end thereof, is connected to a ground point at a second end thereof, and resonates in a substantially ¼ wavelength mode in a first communication frequency band. A feed line is connected between a first feed point and a predetermined position between the first end and the second end of the first radiating element. The second radiating element has a first end that is a second feed point, a second end that is connected to the ground point, and resonates in a substantially ½ wavelength mode in a second communication frequency band. A distance from the ground point to the second feed point is longer than a distance from the ground point to the first feed point.
