N2 - This paper proposes a new wideband DRA design implemented with unit cells which facilitates prototyping using 3D printing. In this design, a rectangular DRA was divided into multiple small blocks. Each block was assigned with a different permittivity based on the material profile optimized through a genetic algorithm. As a result, the proposed compact DRA design gives 68.8 % (4.04 - 8.28GHZ) of impedance bandwidth at S11=- 10 dB, which is significantly higher than the bandwidth of the original bulk DRA.
