APPENDIX A – MICROSTRIP ANTENNA ANALYSIS USING PCAAD VERSION 6.0 [7]
THE NUMERIC RESULTS OF THE MICROSTRIP ANTENNA DESIGN EXAMPLE OF TABLE IV WERE USED AS THE INPUT DATA FOR THE PCAAD
TRANSMISSION LINE MODEL SOFTWARE ANALYSIS.
THE PCAAD ANALYSIS IS PRESENTED IN TABLE A-I BELOW. NOTE FROM THE
'SPLASH SCREEN' RESULTS THAT THE RESONANT FREQUENCY IS PREDICTED TO BE 5.7 GHZ AS OPPOSED TO THE DESIGN CENTER
FREQUENCY OF
5.8 GHZ. THE INPUT IMPEDANCE AT RESONANCE IS 213 OHMS WHICH IS WITHIN ACCEPTABLE LIMITS CONSIDERING
THE SIMPLICITY OF THE TRANSMISSION LINE MODEL.
THE DIRECTIVITY IS PREDICTED TO BE 7.0 DB WHICH SUPPORTS THE
CALCULATED DIRECTIVITY OF
7.0 DB AND THE EM SIMULATION OF GAIN RESULT AT 6.86 DB. THE EM SIMULATION RESULT
INCLUDES THE EFFECTS OF IMPEDANCE MISMATCH LOSS AND FEED LINE IMPEDANCE TRANSFORMER LOSS.
