I have attached the radiation pattern of my design simulated in HFSS.what is inffered from this pattern.how shall i explain my pattern to others.

Re: what could is infered from this radiation pattern

What I infer from these patterns is that your antenna sucks. There is no point on the graphs where the gain is positive. Perhaps also post your model to get better input.

I have attached my model here

i have attached the radiation pattern of four different types of antenna.what that does the value
18,19,20,22 denotes

I presume this are your own simulation results. You should tell us what rETotal is and what's the generator power.

retotal represents the radiated power in electric field direction ,how to know the generated power .
 

I asked for generator power, the power send to the antenna. A parameter of your test setup.

I realize that dB(radiated power) makes no sense without a reference quantity, I'm not familiar with HFSS and don't know how they scale it. Antenna gain would be a commonly understood quantity.
