Problem on drawing equangular spiral antenna on HFSS v10

equation based curve hfss

i'm trying to draw an equangular 2-turn spiral antenna for my thesis on hfss v10
does anybody know how to draw it? i couldn't draw exactly what i want
i just could draw rectangular spiral which i dont need
by the way
my spiral has this parameters:

r= p0*e^(-a*phi0)*e^(a*phi)

x=r*cos(phi)

y=r*sin(phi)

p0<phi<p0+4*pi

all the helps are appreciated
thank you

hfss antenna

any help?

spiral antenna equation

equation based line!
draw the section face.
then sweep along line

sinuous antenna

how do i write it as an equation based line?

Drawing an Equation-Based Curve
Any line that can be described by an equation in three dimensions can be drawn.

1. On the Draw menu, click Equation Based Curve .

2. The Equation Based Curve dialog box opens. Enter the equations for the X, Y, and Z components of the curve in terms of parameter _t. Use the ellipsis (...) buttons to open an Edit Equation dialog box which allows you to select from the available functions, operators, and quantities.

3. Enter the lower and upper bounds for the parameter _t.

4. Enter the number of points to be used to analyze or compute values along the line segment.

5. Click OK on the Equation Based Curve dialog box.

The Properties dialog box appears, enabling you to modify the object’s attributes.

6. Click OK on the Properties dialog box.

Added after 1 minutes:

you cannot use a software without consult its help document

the help ducoment included all the command to draw different shapes

hfss draw spiral

anyone have hfss file of sinuous antenna! please!!!!

Hi have you managed to convert this into formate for "Equation based curve"?

solve in problem in hfss version 10

Can I do an sprial antenna array by HFSS? I would like to know How can I do the feeding? Any idea plz. help

drawing spiral

only chooze the duplicate move to have an array. then you can change the array excitation by: HFSS\edit source

Re: drawing spiral

can you give me example how using equation based curve until the line is there..??
