Abstract

A planar antenna device is mounted on a board including a dielectric layer and two conductor layers vertically sandwiching the dielectric layer. The upper conductor layer includes a first radiating element having an end portion connected through a via hole to a ground formed by the lower conductor layer, a second radiating element having an open end portion, first and second ground conductors connected to respective base portions of the first and second radiating elements via resistors, and a feeder line configured to feed power to the first and second radiating elements.
