How can I fix the graphical outcome of my Reflection Coefficient?

Hello, 

I ran a simulation on a coil antenna with a wire port. The range of the frequency was 1 MHz to 20 MHz. 

On my first simulation I set the number of frequencies to 100 with frequency increments of 191.919 kHz and these were the results:

After running a few more simulations, in attempt to make the graph "smoother" and more accurate, I set the number of frequencies to 500 with frequency increments of 38.076 kHz (this simulation had the same range of 1 MHz to 20 MHz) and these were the results:

Does anyone know why there are multiple "spikes" in my data? How can I fix this problem? 

I have attached a PPT with the data collected in between these results and a copy of my model. 

Thanks,
