The number of frequency appeared in the literature. In [17] authors present a slot on the bands is given by the sum of bands given per each radiator which ground plane to make the ground plane resonant at the same fre- can be controlled independently.

Finally, a concept featuring a from 800–1230 MHz approximately is obtained, small footprint (39 11 mm ) and low profile (2 mm) is proposed that is, an antenna that fulfills at least the standards GSM850 for multiband operation.
