Abstract
En 中文
Design and experimental results of a dual-frequency folded reflector antenna are presented. With an effective diameter of 180 mm and a depth of 60 mm, gain values of 25 and 30 dB at 20 and 30 GHz, respectively, have been achieved. Beamwidths are 6.2 degrees at 20 GHz and 3.7 degrees/4 degrees at 30 GHz.
