T he curves are properly placed in Cartesian coord inates. T he iterative algorithm is u sed to qu ickly calcu late the radiation patterns. Bo th T erdragon and T erdragon-6 have the desirab le property o f low- side lobe, hav ing no grating lobes even when the m in mi um spac- ing betw een elem ents reaches one-w avelength. A s the iteration num ber increases, the m ain lobe becom es narrow er, the ro lloff becom es steeper, and the side lobe becom es low er. On the other hand, as the spac ing betw een the ele- m ents increases, the sam e phenom enon occurs.
