Enhancement of Numerical Computation Methods Useful for Radio Communication Antenna Systems

摘要

The radiation from a flanged parallel-plate waveguide is solved efficiently by the moment method, where the expansion functions contain the correct edge behavior of the fields. This computation method can be useful to optimize radiation of microwave transmitters and efficiency of receiver antenna and front end circuits. It is shown that three appropriate expansion functions are sufficient for an excellent accuracy and convergence rate of the solution.
