Microstrip fractal patch antenna for multi-band communication

Investigation of Mutual Coupling Effects in Conventional and Fractal Capacitive Coupled Suspended RMSAs

“…To reduce the size of planner antenna, number of methods have been developed and reported [14][15][16][17][18][19]. It may be noted that the defects in the patch metallization lead to noticeable radiator miniaturization [14].…”

“…One of the solutions to above limitations can be reached by means of fractal curves. It has been reported in [18,19] that the application of space filling fractal curves enables us to achieve considerable miniaturization and also wideband and multi band properties. Figure 2 shows examples of fractal geometries proposed by Koch (1904) and Sierpinski (1916).…”

Design and Implementation of Printed Micro strip Fractal Antennas for Wireless Applications

“…As already mentioned the fractal antennas employ the fractal geometry for their design as compare to classical antennas which employ Euclidean Geometry [1] . The two basic properties of fractals provide distinguish features to these fractal designed antennas, these are discussed with appropriate application areas below: 1.…”

Stacked multiband fractal patch antennas

“…In [l] - [3], the Sierpinski triangle gasket is used to make multiband monopole and dipole antennas. In [4], the Sierpinski carpet geometry is obtain multiband frequency operation. As a result, three different frequency bands have been obtained at I.SGHz, 4.5GHz and 13.5GHz.…”

“…. This is 1/9 the area of the multiband fractal patch antenna in [4]. As a substrate, copper clad 62mil thickness of Rogers RT -Duroid 5880 ( E , = 2.2) is used.…”
