Abstract
An antenna module radiates radio waves upon receiving a radio-frequency signal output from an RFIC. The antenna module includes flat radiating elements that radiate radio waves in a first polarization direction, feed conductors that each supply a radio-frequency signal from the RFIC to an associated one of the radiating elements, and a ground electrode disposed opposite the radiating elements. As viewed from the RFIC, frequency characteristics of an impedance of the radiating element are different from frequency characteristics of an impedance of the radiating element. 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 radiating element partially overlaps the operable band width of the radiating element.
