PURPOSE:To obtain necessary characteristics, by supplying the power through plural delay lines to plural radiators placed on the straight line, and extending the delay line without changing the space between the radiators. CONSTITUTION:Two delay lines 3-1, 3-2 are provided in parallel with plural radiators 1-1-1-4 placed on the straight line. A space S of length of the delay lines is proportional to a space (d) of the radiators. In this case, since the adjacent radiators receives the power supply alternately from the two delay lines, the radiator space and the delay line length become 2 times comparing with the power supply from one delay line. Accordingly, the length from a distributor 5 to a directinal coupler 2-2 is lengthened by S comparing with the length from the distributor to a directional coupler 2-1. As a result, it is possible to constitute a line which has not been realized mechanically since its length is short in case of one delay line. |
