Development of Hybrid Fractal Tree Antenna Using Modified Koch Curve

An optimized design of printed hybrid fractal tree (PHFT) antenna based on binary fractal tree geometry is presented and discussed. In this work miniaturization has been achieved by inserting a modified Koch curve in the conventional fractal binary tree. The geometrical descriptors of the proposed antenna have been synthesized using Bacterial Foraging Optimization (BFO) and Particle Swarm Optimization (PSO) for optimizing the values of electrical parameters within specifications. A performance comparison has also been done for both of these computational techniques. Representative results of optimized PHFT antenna for both simulations and experimental validations are reported in order to access the effectiveness of the developed approach for reliable implementation in wireless telemedicine applications.
