摘要： A wireless device according to one aspect of the present invention includes an antenna, a focuser, and an absorber. The focuser includes a first and a second region. One of the regions transmits radio waves, and the other blocks them or changes their phase. In a plan view from the antenna, the shape of the first region is a circle and the shape of the second region is an annular ring with an inner diameter equal to the diameter of the first region. The antenna is on the center axis of the circle. A part of the absorber is present between a first plane where the antenna is present and a second plane on which the second region is present. The absorber is present at a position away from the antenna by the outer circumference of the annular ring or longer in a direction perpendicular to the axis.

摘要： According to an embodiment, a signal conversion apparatus includes a control information generator and a selector. The control information generator generates first control information based on rate information indicating transmission rates of original signals. The first control information designates a first timing at which each of the original signals is sampled. The selector selects each of the sampled signals at a timing based on the first timing. The original signal group includes a first original signal at a first transmission rate and a second original signal at a second transmission rate. The first transmission rate is higher than the second transmission rate. The frequency of allocating the first timing to the first original signal is higher than a frequency of allocating the first timing to the second original signal.
