| Abstract: | An approach is developed to analyze microstrip antennas on finite chiral substrates using the finite-element method (FEM). The perfectly matched layers (PMLs) in the chiral media is employed in this work. First, the characteristics of microstrip antennas on infinite conventional, ferrite, and chiral substrates are respectively analyzed in order to validate our analysis. Then microstrip antennas on finite chiral substrates are investigated as a comparison with those on infinite chiral substrates. Finally, the input impedances of microstrip antennas on infinite and finite chiral substrate are calculated. © 2003 Wiley Periodicals, Inc. Int J RF and Microwave CAE 14: 49–56, 2004. |
