A novel wideband inverted Sinc shaped printed monopole antenna is proposed for wireless devices. The proposed configuration not only realizes the monopole antenna in compact form but also depicts good radiation characteristics for wideband operations. A detailed parametric study has been carried out for different size of the ground plane, feed gap and Sinc strip length. By selecting the proper dimensions of ground plane, feed gap and Sinc strip length, the broadband operation for the proposed design can be achieved and the obtained impedance bandwidth covers the 2855-5081 MHz band. The proposed monopole antenna provides a wide frequency band of about 56% for wireless operation. The peak gain and efficiency of the proposed antenna are 4.05 dBi and 92.20 % respectively. Finally a prototype model is developed for the most effective configuration and the simulated results are validated experimentally. It is seen that the proposed antenna occupies small area and is suitable for operation at radio navigation, space research, amateur radio, aviation, public safety mobile, fixed mobile and fixed satellite communication frequencies.
