i have made a modification to it, it is now 1/4 wavelength monopole.
the simulation output is : source voltage= 3092 at -89.79 deg. and
impedance= 11.08-j3092 ohm . what is the meaning of this source
voltage? i have placed a source with amplitude 1v at 0% from E1 because
it is a monopole, the ground type is free space.


Something must be wrong with your model. A resonate 1/4-wave monopole
should have the resistance component around 20-ohms or so.
Additionally, it would appear by the high reactive component you give
that you do not have a ground plane included in you model. A 1/4-wave
monopole requires something to work against.
