Abstract
On an antenna forming face () in a rectangular shape which a dielectric base (A) has, a linear element (A) is provided adjacently only peripheries (, and) of the antenna forming face (). From the linear element (A), a linear conductor () for matching impedance branches. Since the linear element is adjacent to only the peripheries (, and) of the antenna forming face (), portions of the linear element (A) do not become adjacent to each other. Accordingly, mutual interference which easily occurs when the portions of the linear element (A) are adjacent to each other does not occur, so that decrease of radiation efficiency of the dielectric antenna (A) and hindrance to widening a band thereof can be eliminated as much as possible.
