Building a Macromodel of the Satellite Antenna Equivalent Electrical Circuit
P. 309–310.
A formal method is proposed for constructing a macromodel of a linear equivalent electrical circuit of a communication satellite antenna. The macromodel can contain as many phase variables as the antenna designer wants. The macromodel maintains a simple dependence of its output characteristics on the design-technological variable parameters of the antenna model. The use of this approach allows reducing the complexity of calculations by several orders of magnitude.
