Multiband and Compact Fractal Antenna for Wireless Communication

Maheshkumar Ninu Patil, Bhagwan Swaroop Sharma

Antennas with low profile, compact size, multiband are in great insist in modern telecommunication system. Fractal antennas are simple, light weight and compact in size. Sierpinski carpet geometry based rectangular patch fractal antenna is described in this paper. Multiband antenna offers multiple telecommunication services in to single device. This leads to design multiband fractal antenna for wireless communication systems. Here, microstrip line feed method is used to excite the antenna. It is found that increase in number of iterations, number of resonant frequencies increases. This paper presents the design of fractal antennae on FR-4 substrate with dielectric constant 4.4 up to second iteration. The dimension of antennae is 13.5mm x 18mm and operates in frequency band between 4 GHz to 12GHz.
