A FORTRAN Program for Rectangular Microstrip Antennas.

摘要

This report supplies a program, with examples, for the analysis of rectangular microstrip antennas. The formulas upon which the program is based are also provided. The theory from which these formulas were obtained is based on the 'cavity model' of the microstrip antenna developed at the University of Illinois by Lo, Richards, et al. Details of the theory can be found in the references listed in the bibliography at the end of the report. The first chapter contains the formulas and the definitions of the electrical and geometrical parameters used in the program. Chapter two lists the FORTRAN program which implements these formulas. Chapter three contains examples of the program's use. It includes an example which illustrates the use of the two-port analysis feature of the program to determine the 'tuning range' that a variable capacitor loading one port would have to have in order for the radiator to produce any polarization from left hand circular to right hand circular.
