<p>[Abstract] Provided are a substrate for an antenna device and an antenna device for which flexible adjustment is possible for each of resonance frequencies which have been caused to be multi-resonant, and which can be made small and thin. The present invention is provided with a substrate main unit (2), first to third elements (3 to 5), ground surfaces (GND), and ground connection patterns (6), wherein: the first element is such that a feed point (FP) is provided upon a proximal end thereof, and the element has and extends a feed-side passive element (P0), a first connection unit (C1), and an antenna element (AT); the second element is connected to and extends the first element via a second connection unit (C2); and the third element is connected to and extends the first element via a third connection unit. The first element is spaced apart from and extends each of the second and third elements and the ground surface so as to be capable of generating a stray capacitance between each, respectively; and the first element and/or the second element and/or the third element is patterned from the front surface across to the back surface of the substrate main body via through-holes.</p> |
