PCAAD 5.0 is a Windows-compatible antenna analysis, modeling, and design software package. It contains more than 40 separate routines treating wire antennas, aperture antennas, microstrip antennas, arrays, and transmission lines and waveguides. These routines are integrated into a menu-driven, user-friendly system allowing you to quickly evaluate impedance and patterns for a wide variety of antenna types. Some of the new features in Version 5.0 include the following:
• 3-D color pattern plots
• Impedance matching with Smith chart
• Analysis of circular planar arrays
• V-dipole antenna analysis
• Wire loop antenna analysis
• Log periodic dipole array analysis
• More general wire antenna geometries
• Ability to copy graphs to Windows clipboard
• Improved error checking
• Movable labels on pattern and Smith plots
• Improved plot resizing
• Color settings can be saved
• All wire geometries can be viewed in 3-D
• Plotting of E/H or E-theta/E-phi patterns
• Improvements to user interface
• Antenna Short Course included on CD
Apparent problem with PCAAD 5.0, using the linear array pattern synthesis routine: whenever I input anything into the pattern value boxes, the program crashes with a "subscript out of range" error. Is this a bug, or am I doing something wrong?
