  • 발행 : 1986.10.01

초록

The cassegrain antenna, 32metor , diameter, is designed for the satellite earth station at Boun. It is fed by a beam waveguide of type. The results of measurements G/T (Gain to Noise Temperature ratio) is 40.86dB/K at the elevation elevation angle 5˚ for 4GHz. And the average transmit and receive gain are 64.62dB and 61.3dB, respectively. They satisfy the values designed for the antenna. The sidelobe levels of the pattern also are in good accord with the recommendation of C.C.I.R.
