dear rfice,

fractal wire antennas are not narrowbadn and they are logperiodic either,
but, as erregular resonators, microstrip fractal antennas have inherently more Q than euclidian ones. however, an ordinary rectangular MPA, feeding by probe has only about 1% bandwidth also, and by proper feeding, they achieves as much bandwidth as 67%!, this is the case for fractal ones, too.

urs, mamadreza
