Abstract
An antenna body is configured to comprise a dielectric member including a planar radiating conductor and a feeder. The radiating conductor is configured by combining a first forming element and a second forming element so as to share one portion, the first forming element having a circular shape, and the second forming element having a semi-oval shape. The feeder is connected to the radiating conductor at a peripheral portion in the second forming element, which is located on a side of the second forming element seen from the first forming element.
