Abstract

This paper evaluates reconfigurable specification of the fractal tree antenna. Fractal tree antenna fed by a 50 ohms round coax from its middle. Making PIN-diodes on or off state, the characteristic of antenna changes and it results changes in the operation frequency and radiation pattern. The proposed antenna demonstrates reconfigurable frequency range from 1.51 GHz up to 8.6 GHz. Analysis of the antenna has been done by means of commercial software CST Microwave Studio to discuss the impression of different dimensional parameters by controlling the PIN diode switches on radiation pattern, directivity and operational frequency.
