Development of a Modified Hilbert Curve Fractal Antenna for Multiband Applications

Comparative analysis of hybrid fractal antennas: A review

“…Space filling property helps to reduce the size of antenna, that is, miniaturization of antenna by improving the effective permeability and permittivity of the substrate, 10,11 whereas, self-similarity is useful to attain the multiband/wideband characteristics. 12,13 The most common geometries which are used in designing of FAs are Sierpinski Gasket/Carpet, [14][15][16][17][18] Giuseppe Peano, [19][20][21][22][23] Minkowski, [24][25][26][27][28] Koch, [29][30][31][32][33] Hilbert, [34][35][36][37][38] Meander, [39][40][41][42][43] and so on. Apart from this, other fractal geometries are Amer and Sunflower fractal.…”

Bandwidth Enhancement of Cross-Shaped Fractal Antenna Using Lanthanum Doped Ba-Sr Hexagonal Ferrite As Substrate Material For X-Band Applications

“…Depending upon the literature survey prepared in this concern; it is perceived that there are many shapes of fractal structures that are used in antenna designs such as Koch snow ake, Sierpinski carpet, Sierpinski gasket, Minkowski fractals, Moore, and Hilbert curve along with some different shapes over a period of time [7][8][9][10][11][12][13]. In addition, various researchers have presented some ideas related to cross, plusshape, and Chaucer shape fractal antennas due to their simple geometries.…”

“…It is observed from above literature that ferrite substrate provides exibility to microstrip patch antenna designs with different compositions of materials. Also, it is examined from earlier discussion that fractal geometries offer many advantages as compared to simple microstrip patch antennas [6][7][8][9][10][11][12][13].…”

“…Fractal structures are preferred because of their main properties such as selfcorrelated, space-lling, and fractional ratios. Thus, fractal antennas are more bene cial over conventional microstrip patch antennas because they provide multiband/broadband behavior along with size miniaturization [6][7][8][9][10][11][12][13].…”

Meander And Koch Hybrid Fractal Curve Based Dual Hexagonal Radiating Patch Antenna For Quad Band Wireless Applications

“…Whereas, another important property is bene cial to achieve the wideband/multiband characteristics [12,13]. The shapes which are most commonly used in generating the fractal antennas are Koch [14][15][16], Minkowski [17][18][19], Sierpinski Gasket and Carpet [20][21][22], Hilbert [23][24][25], Giuseppe Peano [26-28], Meander [29][30][31], etc. All the discussed fractal shapes have their inimitable implication in the design of antennas for de nite wireless standards.…”
