Abstract: An antenna module includes a first power feed element and a second power feed element each having a flat plate shape, and a ground electrode (GND) arranged so as to face the first power feed element and the second power feed element. The first power feed element is configured to radiate a radio wave having a first direction as a polarization direction. The second power feed element is arranged between the first power feed element and the ground electrode (GND), and is configured to radiate a radio wave having a second direction as a polarization direction. A frequency of the radio wave radiated from the first power feed element is higher than a frequency of the radio wave radiated from the second power feed element. An angle formed by the first direction and the second direction is greater than 0° and less than 90°.

Abstract: A transmission line (12) includes a multilayer substrate (20), a signal pattern line (30), a ground pattern conductor (50), and an intermediate ground pattern conductor (40) that is arranged between the signal pattern line (30) and the ground pattern conductor (50) and that is electrically connected to the ground pattern conductor (50). The signal pattern line (30) has a first connection point (30c) to which a signal conductor extending in a laminating direction of the multilayer substrate (20) is connected. A first cavity portion (41h) is formed in the intermediate ground pattern conductor (40) at a position overlapped with a first end portion (30a) of the signal pattern line (30) in a plan view of the multilayer substrate (20). A first end edge (41e) of the first cavity portion (41h) has a first overlapping portion (41a) overlapped with the signal pattern line (30).

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 module includes a power supply element and a ground electrode (GND) arranged so as to face the power supply element. In a plan view of the antenna module from a normal direction, when a minimum distance along the first direction between a center of the power supply element and an end portion of the ground electrode (GND) is defined as a first distance, a minimum distance between the center of the power supply element and an end portion of the ground electrode (GND) is defined as a second distance, and a distance between the end portion of the ground electrode (GND) and an end portion of the power supply element in the second distance is defined as a third distance, the first distance is longer than the second distance, and the third distance is shorter than ½ of a size of the power supply element.

Abstract: A flexible substrate includes a dielectric having flexibility, a first line, a second line, and ground electrode. The dielectric has a first surface and a second surface opposed to the first surface. The first line , the ground electrode, and the second line are laminated in this order in layers from the first surface to the second surface. When the flexible substrate is seen through from the thickness direction of the flexible substrate, the first line has a line-symmetrical portion that is line-symmetrical with respect to the second line with a virtual intermediate line (LM) serving as a symmetric line.

Abstract: A first RF radiating element is transmissive to visible light and includes a first electrode and a second electrode. The first electrode is formed of at least one linear conductor. The second electrode is formed of a material having a visible light transmittance greater than the visible light transmittance of a material forming the first electrode. The conductivity of the second electrode is smaller than the conductivity of the first electrode. The first electrode and the second electrode face each other in a stacking direction (Z). The first RF radiating element includes a first region, in which the first electrode overlaps the at least one linear conductor, and a second region (TR), in which the first electrode does not overlap the at least one linear conductor, in plan view of the first RF radiating element in the stacking direction (Z).

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.
