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 layered stripline filter has input and output electrodes formed on a dielectric layer, two resonant elements disposed on the dielectric layer and having ends connected to a ground electrode, providing a quarter-wave stripline resonator, an inductive coupling adjustment electrode disposed on the dielectric layer intermediate between the two resonant elements and having opposite ends connected to the ground electrode, and a coupling electrode disposed on the dielectric layer in overlapping relationship to portions of the two resonant elements. The layered stripline filter is small in size and has a desired bandwidth achieved by adjusting the inductive coupling between the two resonant elements. The layered stripline filter has an attenuation peak spaced from the passband thereof, resulting improved attenuation and spurious characteristics.
