It is seen from Eq. (50a) that the curve R/Z~ = constant is a circle with its center on the positive real axis at (R/zo)/ (1 + R/ZO) Every such circle is tangent to the [ine and radius 1/(1 + R/ZO). I’~. = 1 at its point of intersection with the real axis. The circle corresponding to R/ZO = 1 passes through the origin and enc[oses a[l the circles for which R/ZO > 1.

There are many types of charts, of which two, the 1 so-called circle diagrams, will be discussed here.

The absorption and scattering cross sections are then both equal to zero. Similar phenomena can be observed ~vith more genre-al types of antennas. The phase betJ~een the primary and secondary induced antenna distributions is determined by the load impedance and the line length. If the load reflection coefficient is unity, the component distributions on the antenna w-ill be comparable in magnitude, and by suitable adjustment of the line length their relative phase can be adjusted to give a minimum scattering muss section.
