Abstract
According to one embodiment, simulating the mutual performance of an antenna array coupled to an electrical drive circuit includes receiving one or more cross-coupling matrices and a number of electrical circuit parameters. Each cross-coupling matrix comprises matrix elements that each represent a cross-coupling factor of one antenna element to another antenna element of the antenna array. The electrical circuit parameters model one or more characteristics of the electrical drive circuit. Performance of the microwave antenna array and the electrical drive circuit in a far-field environment is modeled according to the electrical circuit parameters and the cross-coupling matrices.
