In this work, a Sinc shaped printed monopole antenna is proposed for wireless devices. The radiating element is a strip monopole configuration folded in the shape of a Sinc function where the radiating element is an extension of 50 ? microstrip line. The proposed antenna not only represents a compact configuration but is easier to design and feed. Several configurations of truncated Sinc(2x) monopole geometry are taken into consideration to show the resonance behavior at single, two or more than two frequencies for multifrequency operation. The detailed parametric study has been carried out in terms of several truncated Sinc configurations, ground plane size, feed gap and Sinc strip length to achieve the desired band of operation. The design formula is also presented for the proposed monopole antenna. Finally, a prototype model is developed and the simulated results are validated experimentally for a particular configuration. It is seen that the proposed antenna occupies small area, depicts good radiation characteristics and is suitable for wireless devices operating at DCS/PCS/IMT-2000/UMTS frequencies.
