Abstract: An antenna module includes dielectric substrates whose normal directions are different from each other, emitting elements disposed on the dielectric substrate, and emitting elements disposed on the dielectric substrate. The emitting element and the emitting element are capable of emitting radio waves of a first frequency band. The emitting element and the emitting element are capable of emitting radio waves of a second frequency band higher than the first frequency band. The emitting element is disposed adjacent to the emitting element in a case where the dielectric substrate is viewed in a plan view from the normal direction. On the dielectric substrate, the emitting element is disposed at a position that is farther from the dielectric substrate than the emitting element is.

Abstract: A communication device includes: an antenna module that radiates a radio wave of a frequency higher than 6 GHz; a mounting substrate to which the antenna module is connected; and a housing that accommodates the mounting substrate. A display screen is formed on a portion of the housing. The housing includes a first surface and a second surface and has a substantially rectangular shape including a first long side, a second long side, a first short side, and a second short side in plan view in a normal direction of the first surface. The display screen is formed on the second surface side. The antenna module is arranged along the first long side of the housing and radiates a radio wave in two directions that are a normal direction of the first surface and a normal direction of a lateral surface along the first long side.

Abstract: An antenna element includes a dielectric substrate, a radiation electrode, a first ground electrode, a second ground electrode, and a via conductor that connects the first ground electrode and the second ground electrode to each other. The dielectric substrate includes a flat-plate-shaped first part and a second part that is thinner than the first part. The radiation electrode and the first ground electrode are arranged on or in the first part so as to face each other in the thickness direction of the first part. The second ground electrode is spaced apart from the radiation electrode. The second ground electrode is arranged on or in the second part so as to not face the radiation electrode in the thickness direction of the second part. The radiation electrode is capacitively coupled to the second ground electrode and the via conductor.

Abstract: In an antenna array of the present disclosure, in a plan view from a direction that is normal to an isolation element, the isolation element is formed between a first antenna element and a second antenna element. A first distance between the first antenna element and a first ground electrode is different from a second distance between the isolation element and the first ground electrode. A third distance between the second antenna element and the first ground electrode is different from the second distance. In a plan view from a direction that is normal to the first antenna element, the isolation element is spaced apart from the first antenna element. In a plan view from a direction that is normal to the second antenna element, the isolation element is spaced apart from the second antenna element.
