Introduction to PCAAD 6.0 PCaAd 6.0 is a Windows-compatible software package that contains over 45 separate routines for the analysis and design of wire antennas array antennas aperture antennas. microstrip antennas and transmission lines and waveguides These routines are integrated into a menu- driven, user-friendly software package that allows you to quickly evaluate impedance and pattern characteristics for a large variety of antenna geometries. Some of the f Caad 6.0 include the follow A user-friendly windows interface Full 32-bit compiled softwar Ⅴ ery si ry ple and intuitive Fast results for first-cut design Graphic illus Polar. rectangular. and 3-D pattern plots Smith chart, VSWR, and return loss plots for input impedance Data file output for patterns and impedance matrices On-line help Validation examples for each analysis routine A. What's New in PCAAD 6.0 PCAAD 6.0 for Windows contains substantial improvements and enhancements compared to the previous version, PCAAD 5.0 [1]. Some of the specific improvements in this version of PCaad are listed below analysis of diagonal horn antennas hase center calculation for horn antennas analysis of rectangular and circular aperture antennas data for antenna noise temperature calculation of radio link loss calculation of polarization mismatch data for atmospheric and rain attenuation calculation of axial ratio due to amplitude and phase errors calculation of array sidelobe level due to random errors co-and cross-pol patterns for all antennas pattern phase data can be saved to pattern file calculator for useful microwave and antenna functions plot up to five data sets on Smith chart plots log files written for all wire antenna solutions improved accuracy for conical horns arbitrary grid angle allowed in Grating Lobe routine can copy active window to clipboard improved graphics, error checking, and Help Glossary of antenna terms included with Short Course PCAAD 6.0 is intended for use by systems and design engineers, researchers, and stude d a quick solution to a canonical antenna design or analysis problem. Most of the routines in PCAAD 6.0 involve basic antenna elements whose theory and characteristics are thoroughly described in a number of texts on antennas [2]-[9]. All of the solutions used in PCAAD 6.0 are based on these results, or on similar well-established and proven methods B. Disclaimer This software package has been written and tested with care.

Getting Started With PCAAD 6.0 A System Requirements PCAAD 6.0 will operate on PC-compatible computers running Windows 98 Windows 2000, Windows XP, or Windows Vista. PCAAD 6.0 requires a 32-bit operating system, and will not run under windows 3. 1. Best results will be obtained with a color monitor having a resolution of at least 800 x 600. Installation requires a CD-ROM drive. PCAAD 6.0 occupies less than MB of disk space Since PCAAD 6.0 runs under Microsoft Windows operating systems, we assume you are familiar with basic Windows usage. Thus, you should know how to run programs from Windows, how to create and rearrange program shortcuts, how to create, copy, and delete files, and how to use Windows menus, text boxes, and control buttons. It is also helpful to be aware of how to open, close, move, and resize windows B. Installing CAAD 6.0 Installing PCAAD 6.0 on your system is casy. Insert the distribution CD into your CD drive, and execute the SETUP. EXE program that is located on the CD Installation may require Administrator access, depending on your operating system. By default, the setup program will install PCAAD 6.0 into a subdirectory called PCAAD6 in the Windows Program Files directory, but a difTerent directory may be specified, if desired. The setup program will decompress and install all necessary files, and a PCAAd 6.0 entry will be created on your Start Menu, and a PCAAD 6.0 icon will be installed on your desktop PCAAD uses a number of small bitmap files, which are stored in the PCaado\BMP subdirectory. PCAAD60 can be started from the Start Menu, or from the PCAAd 6.0 icon on your desktop The PCAAD 6.0 installation procedure also creates a subdirector PCAADOSHORTCOURSE, which contains Pdf files for an introductory short course on antennas. The course is arranged by Chapters 0 through 7, where Chapter 0 lists the contents and syllabus for the course. Chapters I through 7 provide a basic introduction to antenna theory and design, and include examples, review questions, and problems. The course concludes with the Antenna IQ test. answers to the test and all problens are given in the Answers. pdf file. There is also a short Glossary on commonly used terms related to antenna technology. These files may be accessed from the PCAAD 6.0 Help menu, or directly from the PCAADOSHORTCOURSE directory. The Acrobat PDF reader is required to view the short course files To uninstall PCaAD 6.0, use the add/ Remove programs facility located in the Windows Control Panel. This will properly remove the PCaAd 6.0 systems files from your computer and the registry. Any data files that you created when using PCAAD 6.0 will have to be deleted separately C. The Pcaadoni file PCAAD 6.0 uses a file called PCAAD6. INI, located in the PCaad 6.0 program directory, to set some options and directory locations that are required for proper operalion ofPCAAD Generally you will not have lo modify this file, and, like most INI files, improper entries can cause errors when running PCAAD. here we describe the entries in the PCaad6ini file with their default values Lth to user file director path to system text editor PCAAd bitmap option (0。f,1 data sa (0-don't save: 1-save phase data) default pattern plot type (1-polar; 2-rectangular, 3-3D) default impedance plot type (O-Smith chart; I th angle for pattern plots size for pattern plots azimuth step size for 3-D plots elevation step size for 3-D plots 3D plot type (O-both hemispheres; I-upper only color for data set#1(pattern plots) color for data set #2(pattern plots) olor for angle curso color for plot background color for data set #I(RLVSWR) color for data set #I(RL/VSWR) vertical label on rectangular type of pattern cut for data set #1(Smith plot) color for data set #2(Smith plot) color for data set#3(Smith plot) color for data set #4 (Smith plot) color for data set #5 (Smith plot) The above values are typical entries that are set upon installation, but most of these values will change according to the plotting and color options that are set and saved when using the Plot Default Types and Plot Default Colors options from the Plot menu. It is recommended that the user not directly modify the PCaad6. iNi file except perhaps to set the vertical axis label for the rectangular pattern plot routine 【实例截图】
