The dielectric substrate has a first edge extending along a longitudinal direction of the dielectric substrate and a second edge extending along the longitudinal direction of the dielectric substrate, and the second edge is opposite to the first edge. The antenna element is disposed along the longitudinal direction of the dielectric substrate. The Antenna element has a first end containing a feedpoint and a second end containing an open end. The stub element is disposed between a section of the antenna element having a predetermined length containing the first end of the antenna element and the first edge of the dielectric substrate along the longitudinal direction of the dielectric substrate.

摘要： The electronic device includes a case, an antenna element, a heat source, a heat dissipation member, a heat conduction member, a cooling fan, an exhaust port, and an exhaust duct. The case has a pair of main surfaces and side surfaces. The antenna element is used to perform wireless communication. The heat dissipation member exchanges heat with a cooling wind. The heat conduction member conducts heat of the heat source to the heat dissipation member. The cooling fan generates the cooling wind to be blown to the heat dissipation member. The exhaust port is an exhaust port from which the cooling wind is discharged to the outside. The exhaust duct guides the cooling wind to the exhaust port. The exhaust port is disposed on one of the side surfaces, and the antenna element and the exhaust duct are disposed to overlap each other at least partially in the thickness direction.

摘要： An information processing device of the present disclosure includes a processor, a power source that supplies power, a proximity sensor that detects approach of an object, and an antenna that outputs an electromagnetic wave. The processor sets a maximum power of the electromagnetic wave from the antenna to a first value after the power source starts supplying the power, and then sets the maximum power of the electromagnetic wave from the antenna to a second value greater than the first value when the proximity sensor no longer detects approach of an object that has once been detected by the proximity sensor.

摘要： A multiband compatible antenna that resonates at a first frequency and a second frequency includes: a planar conductor including a feeding portion to which a signal is supplied, a grounding portion, and a slit between the feeding portion and grounding portion. The slit includes a first slit portion extending in a first direction and a second slit portion extending in a second direction intersecting the first direction from an end of the first slit portion. The first slit portion is disposed closer to one edge than a center of the planar conductor in the second direction, and the feeding portion is disposed to a side of the first slit portion closer to the one edge. The planar conductor includes a first element portion and a second frequency portion that resonate at the first frequency and the second frequency, respectively. The second slit portion is disposed in the first element portion.

摘要： An antenna unit includes a conductive ground plate, a first antenna element, and a second antenna element. The first antenna element includes a first end connected to a feedpoint and a second end containing an open end. A part of the first antenna element is disposed along the conductive ground plate. The second antenna element branches off the first antenna element at a branch point on the first antenna element. The second antenna element is disposed between the part of the first antenna element disposed along the conductive ground plate and the conductive ground plate. The first antenna element resonates at a first frequency. The second antenna element and a segment between the first end and the branch point of the first antenna element resonate at a second frequency that is higher than the first frequency.
