摘要： In an antenna, an antenna element interval is reduced without depending on an interval between converters, to widen the range of a phase folding angle to widen a detection angle range. The antenna includes a first antenna element including a feeder line extending from a first converter and a plurality of radiating elements. A second antenna element includes a feeder line extending from a second converter aligned together with the first converter and a plurality of radiating elements. The first and second antenna elements respectively include, at partial line portions of the feeder lines which extend from the converters to closest radiating elements, bend portions which are bent in directions which the bend portions come close to each other. The partial line portions of the first and second antenna elements are disposed so as to be linearly symmetrical about a virtual line.

摘要： Provided is a distributor capable of reducing insertion loss while suppressing a ratio in power distribution among output lines from being changed. The distributor 4 is a distributor that is connected with an input line Lin and output lines Lo1 to Lo3 respectively formed on a dielectric substrate 10 as microstrip lines, and distributes to the output lines Lo1 to Lo3 high frequency power fed from a feeding point to a branching point through the input line Lin. In addition, the distributor 4 is configured to include a stub area 42 that is formed in the input line Lin, is separated from the branching point 41, and has a rectangular shape wider than line widths of a first area La and a second area Lb of the input line Lin. The stub area 42 is arranged in a position where the distance d1 between an edge on the feeding point side and lateral edges 3a on an input side of the output lines Lo1 and Lo3 substantially perpendicular to the input line Lin is substantially equal to (λg/4)×(2n+1) where λg is a guide wavelength and n is an integer.
