Dual-band Loop Feed with Enhanced Performance

This paper is aimed on specific problems of electrically small and deep dish parabolic antennas. Since these antennas may suffer with low efficiency authors de- scribe design and optimization of simple dual-band loop prime-focus feed achieving good efficiency for these antennas. 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 0.5 0.55 0.6 0.65 0.7 0.75 0.8 0.85 0.9 0.95 1
