Abstract

PURPOSE:To increase the performance of antenna by satisfying the supplied power and the shape of equiphase face, through the setting of limit to the left and right array distance from the power supplied point with strict solution of the behavior of reflecting and progressing wave at the power supply. CONSTITUTION:The narrow surface of each waveguide 1 has a number of slots with a given distance SI, SII, and the arrays I, II left and right are made on one waveguide 1. In the center power supply nonresonance interval slot antenna, the equiphase surface can be flat on the entire array and a limit is given to the intervals SI and SII. Where SI is expressed in equation 1 as to in-tube wave length lambdag and an arbitrary positive number delta and SII is expressed in equation 2.
