Abstract: Ambient computing is a rapidly growing field which requires increasing number of wireless devices. In this paper first a hexagonal shape patch antenna is designed. Fractal concept is used to achieve miniaturization. So triangle inscribed hexagon fractal patch antenna is designed. The designed antenna is simulated using Computer Simulation Technology (CST) Microwave Studio software. The proposed antenna resonates in the range of 2 GHz to 10 GHz. Mechanical tuning in frequency is achieved by varying the ground length. Good reflection coefficient less than -10dB, gain, E and H fields are observed in CST. Then fuzzy logic model is developed in MATLAB software for movable ground. Mechanical sliding ground results and fuzzy logic model results are compared. This antenna is adaptive and anticipatory, can be utilized where stable system is required because it provides more robustness. This paper explores the use of fractal reconfigurable antennas to aid the development of ambient computing.
