A Novel Band-Notched UWB Conformal Antenna Combined with the Method of Circuitry

Abstract

This paper introduces a wide conformal quasi printed Log Periodic dipole band-notched antenna. The conformal band-notched antenna is composed of three sections-the low frequency structure, the band-notched structure and the high frequency structure. Installing to the interior of a radome, radiation characteristics of the antenna are very good. The simulation results revealed that the antenna has good VSWR(less than 2) and radiation pattern of realized gain over the design frequnecy range of 3GHz to 6.2GHz and 8GHz to 12GHz.
