Patent abstract
A wideband slot antenna according to the present invention is a ¼ effective wavelength slot antenna in which a ground conductor 103 having a finite area is allowed to function as a dipole at lower frequencies. An inductive region 123 is provided within an feed line 113 in a region intersecting a slot 111, and an antenna feed point 117 for connection to an external unbalanced feed circuit is provided at a position which satisfies high impedance conditions for an unbalanced ground conductor current.
