Abstract :
In this paper, a small chip UWB antenna loaded with PPS resin mixed with metal powder was developed. The metal powder is mixed with PPS to increase the permittivity of the element. The size of the dielectric chip element is 7.4 mm X 10.1 mm X 0.94 mm, on the FR-4 substrate of the size 20 mm X 42 mm X 0.5 mm. The VSWR of the antenna is lower than 2.0 for 3.0-5.0 GHz. The frequency characteristics of the antenna gain and group delay are very flat. An omnidirectional radiation characteristic is obtained at -2 dBi for vertical polarization.
