An 8x1Sierpinski Carpet Fractal linear Array Antenna design for Multiband Applications
Authors
Abstract
Single element antennas in many applications can not satisfy the demands of gain or radiation pattern. A potential alternative may be to incorporate several antenna components in an array. In this article, novel fractal structure-based array antenna architecture, Fractal arrays used to maximise the antenna’s bandwidth and reduce the grid lobes, has been identified. The proposed antenna is usable throughout the 3.1GHz to 10.6 GHz range explicitly reserved for the UWB applications. The proposal involves an 8-element print fractal linear array antenna for wireless communication and multiband deployment working on frequencies between 2.2GHz and 12GHz through minimal ground plane rather than complete ground plane. The Sierpinski Carpet Framework for 2nd Iteration used for the Fractal linear Array configuration of the antenna. He also addresses the Fractal linear antenna architecture measures. The 8- elements linear array and Fractal linear array are designed, simulated and tested by using Vector network analyser and the simulation and the practical results are compared.
