Abstract: A radiation conductor is constructed of a metal plate having a pair of main surfaces pointing in opposite directions. Each main surface of the pair of main surfaces includes a first surface region that includes at least part of a peripheral edge portion of the main surface. At least one main surface of the pair of main surfaces includes a second surface region that is a region other than the first surface region. A dielectric member holds the radiation conductor in such a manner that the first surface region of each main surface of the pair of main surfaces is sandwiched between portions of the dielectric member in a thickness direction of the radiation conductor. The second surface region of the at least one main surface is exposed.

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 ground plane is disposed in a dielectric substrate or on the top surface of the dielectric substrate. A high-frequency semiconductor device is mounted on the bottom surface of the dielectric substrate. A shield structure that is provided in a space closer to the bottom surface than the ground plane is surrounds the high-frequency semiconductor device from below and sideways of the high-frequency semiconductor device and is connected to the ground plane. An opening is formed in the shield structure. A radiation-structure portion causes a high-frequency signal output by the high-frequency semiconductor device to be radiated through the opening.

Abstract: A feed line connects an RFIC and a radiating element. A baseband ground plane (BB ground) is connected to a ground terminal of a BBIC. A radio frequency ground plane (RF ground) is placed in such a manner as to overlap the BB ground. The RF ground serves as a return path of the feed line. A first inter-ground connection circuit connects the BB ground and the RF ground. Furthermore, a second inter-ground connection circuit connects the BB ground and the RF ground. Connecting parts between these grounds and the second inter-ground connection circuit are arranged closer to the edges of these grounds than connecting parts between these grounds and the first inter-ground connection circuit. The connecting part between the ground and the second inter-ground connection circuit is placed on one side of a certain imaginary straight line that passes substantially the geometric center of the ground.

Abstract: A surface-layer conductive plate having an opening is disposed on a first surface of a dielectric substrate. A radiation electrode is disposed inside the opening on the first surface of the dielectric substrate. A ground conductive plate is disposed on a second surface of the dielectric substrate, the second surface being opposite to the first surface. Interlayer connection members are disposed so as to surround the opening as seen in a plan view. The interlayer connection members electrically connects the surface-layer conductive plate to the ground conductive plate and defines a cavity that causes electromagnetic resonance to occur. A reactance element is configured to cause an impedance that a side face of the cavity exhibits with respect to an electromagnetic wave propagating in the cavity to include a reactance component.

Abstract: A first antenna, a second antenna, and a waveguide structure are housed in a single cabinet. An operating frequency of the second antenna is higher than an operating frequency of the first antenna. The second antenna is an array antenna including a plurality of radiating elements. The waveguide structure is present outside a range of a half-value angle of a main beam as viewed from the first antenna, includes a unit waveguide disposed in a route of a radio wave received by the second antenna, and further attenuates a radio wave with the operating frequency of the first antenna.
