摘要： An antenna device comprises an antenna section and a filter section which are formed in an integrated manner in a dielectric substrate, wherein the antenna section and the filter section are coupled to one another via a capacitance. Further, 0.3×Lr≦Lt≦1.2×Lr is satisfied provided that an antenna length of the antenna section is Lt, and an antenna length measured for a single antenna is Lr. Accordingly, it is possible to realize a small size of the antenna device while avoiding the decrease in gain and the disadvantage of narrow band.

摘要： A stacked dielectric filter includes two sets of resonators arranged in a dielectric substrate constructed by laminating a plurality of dielectric layers, in which each of the resonators includes at least two resonance electrodes superimposed in a stacking direction. One of the resonance electrodes of the two resonance electrodes for constructing each of the resonators is formed to have a wide width as compared with the other resonance electrode. Accordingly, even when stacking deviations occur in the plurality of resonance electrodes during the production process, it is possible to decrease the variation of characteristics. Thus, it is possible to maximally exhibit the effect (high Q value, small size, and high performance) to be obtained by constructing the resonator by superimposing the plurality of resonance electrodes in the stacking direction.

摘要： A compact inductor comprises a coil, a coil-burying body, and a body for a closed magnetic circuit. The coil-burying body is a fired porous ceramic body having a first magnetic permeability, in which the coil is buried. In the coil-burying body, “a through-hole 12a passing through inside of the coil along an axis of the coil” is formed. The body for a closed magnetic circuit is a fired dense ceramic body having a second magnetic permeability greater than the first magnetic permeability. The body for a closed magnetic circuit is arranged closely/densely at an outer circumference portion of the coil-burying body and in the through-hole. A magnetic path is therefore formed mainly within the body for a closed magnetic circuit, and the magnetic flux density is reduced in an area close to the coil. Accordingly, an inductor having the excellent superimposed DC current characteristic is provided.
