Claim 0:
1. An antenna module that radiates a radio wave in response to receipt of a radio-frequency signal output from a feed circuit, the antenna module comprising:
a first radiating element that is flat and that radiates radio waves in a first polarization direction;
a second radiating element that is flat and that radiates radio waves in the first polarization direction;
a first feed conductor that supplies a radio-frequency signal from the feed circuit to the first radiating element;
a second feed conductor that supplies a radio-frequency signal from the feed circuit to the second radiating element; and
a ground electrode disposed opposite the first radiating element and the second radiating element, wherein
as viewed from the feed circuit, frequency characteristics of an impedance of the first radiating element are different from frequency characteristics of an impedance of the second radiating element, and
under a condition a frequency band in which a return loss is less than or equal to a predetermined value is defined as an operable band width in each of the radiating elements, the operable band width of the first radiating element partially overlaps the operable band width of the second radiating element.
