ACTIVE ANTENNA APPARATUS FOR MOBILE RECEPTION OF MULTI SATELLITE SIGNAL AND CHASING METHOD

摘要

PURPOSE: An active antenna apparatus for the mobile reception of a multi satellite signal and the chasing method are provided to receive the satellite signal of an another different polarization and receive the desired satellite signal in moving under the existence of the multi satellite signal having same polarization and frequency. CONSTITUTION: A radome(1) protects the system from the outside. A radiation module(2) can receive an electric wave of double polarized wave and a multiple satellite signal. The multiple satellite signal is inputted to the radiation module(2) passing through the radome(1). An active channel module(3) amplifies the received satellite signal as a low noise. A beam formation module(4) controls the phase of a phase displacement device. A multiple satellite chasing controller(9) controls the chasing of the desired polarized satellite signal among the multiple satellite signal when moving.
