A novel CPW fed wearable spear shape antenna is proposed for UWB band applications. UWB Antennas has become a highly competitive and emerging technology in the industry communities of telecommunication. It is useful in monitoring and control the movement of objects and also helps in tracking of the goods in industries without the use of physical contact in a convenient way, but still some radiation ioss occurs. To minimize the radiation loss of the antenna using this system, a compact antenna at 3.1 - 10.8 GHz frequencies is to be designed and analyzed with different substrate such as Teflon and FR4 Substrate to provide the better results efficiently. A study of the understanding of the antenna performance as a function of its dielectric parameters of the environment in which it is affixed was performed. Simulations in various slot widths, structures and dimensions state demonstrate that the antenna covers the complete UWB band frequency of 3.1GHz - 10.8GHz for the wearable applications. This antenna is to-be simulated using CST simulator software and expected to give wide impedance bandwidth, stable radiation pattern and constant gain.
