卫星电视接收天线的主要性能要求与极化调整

Main Performance Requirements and Polarization Modulation of Receiving Antenna of Satellite TV

介绍了卫星天线对于天线增益、频带特性、驻波比、天线噪声、天线方向性等主要性能的要求,并阐述了天线的极化调整,包括只收线极化波时极化器的调整及圆极化器的调整。

This paper introduces the requirements of the satellite antenna for the main performances such as antenna gain, frequency characteristics, antenna noise, antenna directivity, etc. and expounds the polarization modulation of antenna including the modulation of the polarizer that only receives linear polarized waves and the modulation of the circular polarizer.
