The feed structure of the antenna imposes an elliptical polarization singature that is different from the circular polarization expected from a symmetric spiral. We develop a lossy-transmission-line model yielding the measured polarization response. A combination of a balanced and an unbalanced mode is required. Reflected current waves from the arm ends are significant.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=755), last updated on Sun, 25 Mar 2012 18:54:21 -0500" }
