Abstract
Provided is an antenna-device substrate which is capable of flexibly adjusting multiple resonance frequencies, and also provided is an antenna device. The antenna-device substrate is provided with a substrate main body (), a ground plane (GND) on the surface of the substrate main body (), first to third elements (to), and a short part () connecting the first element () and the second element (). The first element is provided with a feed point (FP) at the base end and extends comprising a first connector (C) of a first passive element (P). The second element is connected to the ground plane and is provided with a first antenna element (AT) at the tip end, and extends comprising a second connector (C) of a second passive element (P) and comprising a fourth passive element (P). The third element extends comprising a third connector (C) of a third passive element (P). The first element extends with a gap provided between the first element and each of the second element, the third element, and the ground plane such that a floating capacitance can be generated therebetween.
