You should start by not plotting the grid via functions, but via

	set grid polar

For the remaining details, I highly recommend you have a look at the
example script 'poldat.dem' you received with gnuplot.  The second
plot ("antenna pattern") should be almost exactly equivalent to what
you're trying to do.

Well, you selected "polar" mode, so yes, you data should be in polar 
mode.  Otherwise, turn off 'set polar' and plot them as they are.
