Simulation of Parameters of A Microstrip Array Antenna Based on Equivalent Source

This paper mainly introduces a simulation calculation method of electromagnetic parameters of microstrip antenna array based on equivalent source. The calculation method first determines the active element pattern of the smallest array element, and deduces the pattern of the array composed of super-large and complex array elements that needs to be calculated by means of an equivalent source. The electromagnetic parameter simulation calculation method can greatly reduce the electromagnetic parameter simulation calculation amount of a large-scale antenna array, reduce calculation time, reduce hardware resource requirements, and improve scientific research efficiency.
