Write a Fortran code for rectangular microstrip antenna that works at 9.40 GHz to find ;radiation diagrams, HPBW, F/B ratio, gain parameters.

COMPUTER PROGRAM - MICROSTRIP ANTENNAS THIS IS A FORTRAN PROGRAM THAT DESIGNS AND COMPUTES THE ANTENNA RADIATION CHARACTERISTICS OF: I. RECTANGULAR II. CIRCULAR MICROSTRIP PATCH ANTENNAS BASED ON THE CAVITY MODEL AND DOMINANT MODE OPERATION FOR EACH. THAT IS: A. TM010 MODE FOR THE RECTANGULAR PATCH B. TM110 MODE FOR THE CIRCULAR PATCH **INPUT PARAMETERS 1. FREQ = RESONANT FREQUENCY (in GHz) 2. EPSR = DIELECTRIC CONSTANT OF THE SUBSTRATE & 3. HEIGHT = HEIGHT OF THE SUBSTRATE h (in cm) 4. YO = POSITION OF RECESSED FEED POINT Y. (in cm) RELATIVE TO LEADING RADIATING EDGE OF RECTANGULAR PATCH. NOT NECESSARY FOR CIRCULAR PATCH **OUTPUT PARAMETERS A. RECTANGULAR PATCH: 1. PHYSICAL WIDTH OF PATCH W (in cm) 2. EFFECTIVE LENGTH OF PATCH Le (in cm) 3. PHYSICAL LENGTH OF PATCH L (in cm) 4. NORMALIZED E-PLANE AMPLITUDE PATTERN (in dB) 5. NORMALIZED H-PLANE AMPLITUDE PATTERN (in dB) 6. E-PLANE HALF-POWER BEAMWIDTH (in degrees) 7. H-PLANE HALF-POWER BEAMWIDTH (in degrees) 8. DIRECTIVITY (dimensionless and in dB) 9. RESONANT INPUT RESISTANCE (in ohms) a. AT LEADING RADIATING EDGE (y = 0) 6. AT RECESSED FEED POINT FROM LEADING RADIATING EDGE (y = yo) B. CIRCULAR PATCH: 1. PHYSICAL RADIUS OF THE PATCH a (in cm) 2. EFFECTIVE RADIUS OF THE PATCH ae (in cm) 3. NORMALIZED E-PLANE AMPLITUDE PATTERN (in dB) 4. NORMALIZED H-PLANE AMPLITUDE PATTERN (in dB) 5. E-PLANE HALF-POWER BEAMWIDTH (in degrees) 6. H-PLANE HALF-POWER BEAMWIDTH (in degrees) 7. DIRECTIVITY (dimensionless and in dB)
