Paper Abstract

We present results of measurements of the polarization response of asymmetric spiral antennas coupled to Ni-NiO-Ni diodes, over the wavelength range 10.2 to 10.7 tim. The feed structure of the antenna imposes an elliptical polarization signature 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.
