Abstract: An antenna device includes a ground electrode, a feed element, and a parasitic element. The ground electrode has a substantially non-square rectangular plane shape that includes a first side extending in a first direction and a second side extending in a second direction orthogonal to the first direction. The feed element has a substantially rectangular plane shape and is formed in such a way that each side of the feed element becomes parallel to the first direction or the second direction. The parasitic element is formed in such a manner as to face a side of the feed element parallel to the first side. The feed element is configured to radiate a first polarized wave that excites in the first direction and a second polarized wave that excites in the second direction. The length of the first side is longer than the length of the second side.

Abstract: An antenna module includes a dielectric substrate, a ground electrode, a power feeding element (121) and a power feeding element (122) each facing the ground electrode, and power feeding wirings (141) and (142). The power feeding wiring (141) transmits a radio frequency signal to a power feeding point (SP1) of the power feeding element (121). The power feeding wiring (142) transmits a radio frequency signal to a power feeding point (SP2) of the power feeding element (122). A frequency of a radio wave from the power feeding element (122) is higher than a frequency of a radio wave from the power feeding element (121). The power feeding wiring (142) includes a via rises from the ground electrode side to the power feeding element (122) at a position different from the power feeding point (SP2) and a wiring pattern that connects the via and the power feeding point (SP2).

Abstract: First and second end-fire antennas are arranged on a dielectric substrate. The first end-fire antenna has polarization characteristics being parallel with a first direction. The second end-fire antenna has polarization characteristics being parallel with a second direction orthogonal to the first direction. A patch antenna provided with a first feed point and a second feed point, which are different from each other, is arranged on the dielectric substrate. When the patch antenna is fed from the first feed point, a radio wave whose polarization direction is parallel with the first direction is excited. When the patch antenna is fed from the second feed point, a radio wave whose polarization direction is orthogonal to the first direction is excited. A wireless communication module capable of achieving directivity in a wide range from a direction parallel with the substrate to the direction of the normal to the substrate is provided.

Abstract: A semiconductor component is face-up mounted on a package substrate. An antenna substrate is flip-chip mounted on a front side of the semiconductor component. A device-side high-frequency signal terminal is disposed on the front side of the semiconductor component, and an antenna-side high-frequency signal terminal is disposed on a back side of the antenna substrate. The device-side high-frequency signal terminal and the antenna-side high-frequency signal terminal are electrically connected to each other. Thus, the antenna substrate for high-frequency signals can be separated from the package substrate for baseband signals.

Abstract: An antenna module includes radiating elements that radiate radio waves in a first polarization direction, and a feed conductor that supplies a common radio-frequency signal to the radiating elements. A first radiating element and a second radiating element are disposed adjacent to each other. The feed conductor includes a common conductor, and conductors branching off from the common conductor. The conductors are respectively coupled to the radiating elements. Frequency characteristics of an impedance of the radiating element are different from frequency characteristics of an impedance of the radiating element. Under another condition of 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.
