Simulation Analysis of Harmonic and Spurious Emission Characteristics of Array Antenna

The analysis of antenna emission characteristics and relevant standards of antenna electromagnetic emission is the basis and cornerstone for the study of reasonable limits of harmonic and spurious emission of phased array radar antenna. In order to study the harmonic and spurious emission characteristics of the antenna, this paper uses CST software to model and simulate the planar array antenna at 3G frequency. The far-field pattern of the array antenna is obtained and the emission relationship between the fundamental wave and harmonic of the array antenna is analyzed which can provide experimental guidance for harmonic testing.
