The routine also reads the operating frequency from the data file, but you may enter a different operating frequency, if desired. The feed is specified with two data files for the E- and H-plane patterns; these may be generated through other PCAAD antenna routines. Five PWS modes are used on each dipole. You can enter specific values for these parameters in the appropriate boxes, or allow PCAAD to provide estimates by clicking the Compute button. Broadside Beam phase set to zero on each element Specify Scan Angle progressive phase shift to steer beam to a specified scan angle Specify Phase Shift progressive phase shift applied Data File phase data is read from a specified data file

Circular Probe-Fed Patch Analysis This routine analyzes a circular probe-fed microstrip antenna using a cavity model similar to that discussed in reference [9].

Antenna Design Associates – Software for Antenna Design

Validation 1 Consider a rectangular probe-fed pcaav with a length of 4. One to three modes is usually sufficient for accurate results. This example corresponds to the first case considered in [13]. Rectangular Aperture Antenna Analysis This routine computes the patterns and directivity of a rectangular aperture antenna pcaad 6 a uniform phase distribution and either uniform or cosine tapered amplitude distributions in the E- and H-planes.

Attenuation due to conductor and dielectric loss can also be calculated, if desired. Then enter the parameters for the feed side of the antenna: Begin by entering the bottom layer substrate parameters thickness, dielectric constant, and loss tangentthen the cover layer parameters thickness, dielectric constant, and pcaad 6 tangent.

Pcaad 6 –

These angles are measured from the axis of the dipole, and have default values of 90 broadside. Note that many antennas in PCAAD microstrip antennas, horn antennas, and antennas over a ground plane have volumetric patterns that extend only over the upper hemisphere. Rectangular aperture coupled patch analysis. The geometry of the V-dipole may be viewed in three dimensions by clicking the Show Geometry pcaad 6. Included are analysis and design solutions for microstrip line and stripline, and analysis solutions for covered microstrip line, pcaad 6 line, rectangular waveguide, circular waveguide, and surface waves on a grounded dielectric substrate.

It contains more than 50 routines treating wire antennas, aperture antennas, microstrip antennas, arrays, transmission lines and waveguides, and more.

E— and H—plane sectoral horns. Begin by entering the frequency, the number of dipoles in the x and y-directions, and the spacings center-to-center of the dipoles in the x and y-directions. Before using your VisTablet Page 3 2. Log—periodic dipole array analysis. The routine begins with a dialog box to enter a filename for the wire antenna geometry.

Similarly, the power dissipated in the antenna does not include power lost in the series generator impedances. Add pictures to your poster When computing characteristic impedance, you will enter the dielectric constant, the substrate spacing, and the line width. The routine prints out the maximum phase error at the edge of the pcaad 6 relative to the center of the apertureand the directivity of the horn.

The level of the quantization lobe is also displayed note that this value is given pcaad 6 to the main beam pcaa the array. The file should open with the Acrobat Reader.

PCAAD 2.1 Personal Computer Aided Antenna Design

The routine also computes the main beam pointing angle, the 3 db beamwidth of the main beam, and provides a movable angle cursor to read pattern values at any angle. If you are entering data by hand, use time or the independent variable in.

Grating pcaad 6 diagram pcaad 6 planar arrays. Plots may be printed click the Print Plot button in the plotting windowor copied to the Windows clipboard for use in other applications use Copy Graph from Plot on the main menu bar.

The pattern plot colors match those used in the display boxes at the left of the plotting routine window. Begin by entering the frequency, and the aperture diameter. The Taylor coefficients are computed using the algorithm of reference [20], which is much more ocaad and efficient pcaad 6 large arrays than the null-matching or aperture sampling techniques.

Upon clicking the Compute button, the routine will compute the moment method solution for the dipole, and list the input impedance pcaad 6 frequency in the list box. You also have the option of adding gaussian distributed zero-mean random errors to any amplitude pvaad.

Use the list box to enter the number of bits for the phase shifters.

The gain is computed in terms of the input power to the dipoles, and does not include power dissipated in the generator impedance.
