A wideband flat antenna includes N linear elements consisting of first to N-th linear elements, wherein the length of the (N-1)-th linear element is set longer than the (N-2)-th linear element and the area of the (N-1) linear element is enlarged in the (N-2) or N-th linear element direction or the (N-2) and N-th linear element direction. One power supply point (14a) is provided on the N-th linear element nearest to a ground plate (21) while the other power supply point (14b) is provided on the (N-1) linear element secondly- nearest to the ground plate (21). The vicinity of a conductor (26) of the (N-2)-th linear element is connected to the vicinity of the conductor (26) of the N-th linear element nearest to the ground plate (21) by a first conductor (31). |
