to get current distribution along any antenna numerical method likes MoM, FEM, TLM, .. . can be useful.
I think the best efficient method is MoM for a linear dipole antenna. NEC is a non-commercial software based on MoM to do this.
To calculate power efficiency (PE) you can use these equations easily:
Pout = 0.5*real(V*conj(I)) V:voltage across your main element and I: Current
PDC = real(V_DC*I_DC)
Eff = mag(Pout/pDC)
good luck
Mesh function in MATLAB or HFSS !!??
In MATLAB you can easily use its help to apply any function like "mesh".
for example, this pseudo code in MATLAB is useful to use mesh function,
[X,Y] = meshgrid(-4:.5:2.5, -3:.5:2);
%construct X and Y to depict the function.
Z = sqrt(X.^2 + Y.^2)...
SunnySkyguy it is assumed we want to synthesis a 50-ohm microstrip transmission line,
consider er = 4.4, h (height) = 1.6 mm, freq = 1000 MHz, and t (thickness of trace) = 0.001 mu m.
result by **broken link removed**
W = 3.045654296875 mm
**broken link removed** gave me Z0 = 50.1 ohm...
You can use this links to design or synthesis microstrip transmission lines, all links use closed-form expressions.

I think you want to fine dispersion diagram for evaluating the performance of an EBG structure in CST, this ex can be useful to do this.
