The reflection-type bandpass filter includes a substrate formed by laminating a conducting layer and a dielectric layer, and a microstrip line made of a conductor of a non-uniform width and provided on the dielectric layer. The width distribution of the microstrip line in the lengthwise direction is set such that the absolute value of the difference in reflectivity at the frequency f in the regions f 10.6 GHz and the reflectivity in the region 3.7 GHz≦f≦10.0 GHz is not less than 10 dB, and the variation of the group delay in the region 3.7 GHz≦f≦10.0 GHz is between −0.2 and 0.2 ns.

    摘要： An antenna element (115) of an antenna device has first and second root sections (117) and (118) and an intermediate section lying between the first and second root sections (117) and (118). A feed section (114) is provided in the first and second root sections (117) and (118). The first and second root sections (117) and (118) are arranged so as to surround the feed section (114), and are provided in a wind section (113). Tail end linear parts in the wind section (113) extend in respective opposite directions. At least one of the first and second root sections (117) and (118) has a wider width part, which is formed such that a portion that overlaps a feed line connected with the feed section (114) is larger in width than other portions. This makes it possible to realize high radiant gain and improve a VSWR characteristic for each radio wave.
