Design of Wideband Inverted Sinc Shaped Monopole Antenna

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 at the operating band (2855-5081 MHz). The proposed monopole antenna provides a wide frequency band of about 56% for wireless operation. A detailed parametric study has been carried out for different size of the ground plane and feed gap. 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.
