Abstract

PURPOSE:To decrease the variance in received power, by determining the length of aperture of input and output elements so that the gain of the input and output elements is maximum and the direction of the input and output element so that the received power for two output and input elements is equal. CONSTITUTION:The length of aperture Dt of input and output elements 24 is determined so that the gain of an input and output element 24 is maximum to the direction of two straight lines tying output and input elements and the input and output element 24 across the element group of the output and input elements arrangd on a partial curve. Taking into consideration dielectric loss and conductor loss at a parallel flat plate 1, the direction of the input and output elements and the output and input elements is determined so that the received power of respective two output and input elements or input and output elements across the element group on a partial curve on which the output and input elements and the input and output elements are arranged when they are respectively energized, can be equal.
