Abstract: An antenna module includes a dielectric substrate, a radiating element, and grounding electrodes. The dielectric substrate has a first surface facing a second surface, and includes a plate-shaped first portion and a plate-shaped second portion which has a thickness less than that of the first portion. The radiating element is disposed in the first portion. The grounding electrode is disposed in the first portion at a position, which is located apart from the radiating element in the direction from the radiating element to the second surface, so as to face the radiating element. The grounding electrode is disposed between the first surface and the second surface in the second portion, and is electrically connected to the grounding electrode. The second surface in an area of the second portion includes a recess disposed at an end of the first dielectric substrate.

Abstract: An antenna module includes substrates with different normal directions from each other, a radiating element disposed on the substrate, a radiating element disposed on the substrate, a hybrid coupler, and an RFIC. The hybrid coupler includes input terminals (IN1, IN2), and output terminals (OUT1, OUT2). The RFIC is connected to the input terminals (IN1, IN2) and supplies a radio-frequency signal to the radiating elements. The radiating elements are capable of radiating a radio wave in a first frequency band. The radiating element is connected to the output terminal (OUT1), and the radiating element is connected to the output terminal (OUT2). A phase difference between radio-frequency signals to be supplied to the input terminals (IN1, IN2) is adjusted to fall within a range of greater than −90° and less than 90°.
