In this paper, the authors present a novel single port swastika shaped dotted monopole antenna evolved from a simple circular monopole antenna by introducing swastika shaped slots and the dots in the patch geometry. This antenna behaves as an ultra-wideband sensing antenna which works in the frequency range of 3.6GHz to 8.9GHz .This antenna is further modified by connecting stubs with the switches. By appropriate combination of switches the antenna works as a reconfigurable antenna.
