Abstract
An antenna module includes a radiation element including feeding elements adjacent to each other, a feed wiring, a ground electrode, and a filter circuit. The ground electrode is disposed to face the radiation element. The feed wiring transmits a radio frequency signal from an RFIC to the radiation element. The filter circuit is connected between a feed circuit and the feed wiring. The ground electrode includes a first portion facing the radiation element, and a second portion arranged in a layer at an upper side closer to the radiation element than the first portion. In plan view of the antenna module from a normal direction, i) the second portion is disposed between the two feeding elements, and ii) the filter circuit overlaps the second portion and is disposed in a layer at a lower side than the second portion.
