Advantages and Applications of Fractial Antennas
A Review on Fractal Antenna – IJERT
A wideband stacked microstrip patch antenna …. Conclusions: A thin dual-resonant stacked shorted patch antenna has been presented. The concept of stacking patches is realized through electromagnetic coupling form which gives bandwidth stacked patch antenna thesis enhancement . In the case where the top patch is longer than the bottom one, computations show that the lower resonance is very close to the resonant frequency of the isolated top patch and the upper resonance is determined primarily by the size of the bottom patch.. For dual polarized MIMO antennas, high cross polarization isolation values are desired to separate the transmitting and receiving channels in order to prevent them affecting each other.
Now days, there is highly demand of antenna with these characteristics 1 Compact size 2 Low profile and 3 Multiband or broad band. As well as it have to maintain antenna parameters i. Gain, Efficiency, Return loss, Directivity etc. With advancement in communication technology over the past decade, there is an increasing demand for miniaturization, cost effective, multiband and wideband antennas. Fractal antenna designs can support in meeting these requirements.
There are many applications that can benefit from fractal antennas. The sudden grow in the wireless communication area has sprung a need for compact integrated antennas. The space saving abilities of fractals to efficiently fill a limited amount of space create distinct advantage of using integrated fractal antennas over Euclidean geometry. Examples of these types of application include personal hand-held wireless devices such as cell phones and other wireless mobile devices such as laptops on wireless LANs and networkable PDAs and RFID.
