Miniaturization Of Multiban Patch Antenna Using Stack Configuration
A novel technique for miniaturization of microstrip patch antenna is proposed for portable and multifunctional communication systems. The authors proposed design consists of double fractal patch, PI-shaped slot on fractal patch with first iteration and combination of L-shape and U-shape slots on the ground plane. In this way, they get smaller size antenna which is smaller than the conventional antenna. The most interesting feature of their proposed design is that they are getting multiband response in the frequency range of 1-8GHZ having directivity in the range of 3.76dBi-6.52dBi, good gain and good impedance bandwidth for desired bands.
