ABSTRACT:
A wideband slot antenna according to the present invention is a ¼ effective wavelength slot antenna in which a ground conductor103having a finite area is allowed to function as a dipole at lower frequencies. An inductive region123is provided within an feed line113in a region intersecting a slot111, and an antenna feed point117for connection to an external unbalanced feed circuit is provided at a position which satisfies high impedance conditions for an unbalanced ground conductor current.
