I have designed a folded-shot fractal antenna with single iteration with help of Koch iteration technique to achieve multiband properties. Antenna simulation tool Ansoft HFSS is used to design and simulate. Antenna proposed by me work with six frequency bands with acceptable return loss. Implementation of Folded slot antenna is done over a single slot antenna. Proposed design of antenna offers ...

Design & simulation of fractal triangle microstrip patch antenna done by using IE3D software of Zeland. In this paper, a special technique is proposed to design a new patch antenna, shapes is equilateral triangular fed by a 50...

The paper presents design of three different fractal antennas in Low Temperature Co-fired Ceramic (LTCC) substrate. An aperture coupled feeding technique has been used in all the three designs which is highly suitable for multi-layer system on package (SoP) concept. The three fractal designs demonstrated are Sierpinski carpet fractal antenna, Sierpinski gasket fractal antenna and Koch snowflake...

This paper presents the use of PN junction diode on fractal monopole antenna with microstrip line for rreconfigurable multiband antennas. The developed multiband antennas focus on the applications for Wi-Fi, cordless telephone and satellite & radar. A fractal reconfigurable antenna was designed using the known fractal geometry such as Sierpinski gasket is fed by strip line using coaxial feed. A...

A novel monopole asymmetric fractal micro strip antenna is designed and analyzed in this paper. The proposed Koch fractal monopole antenna is resonating at triband with circular polarization operation. Five diff structures without slot (basic model), single slot (Iteration 1), double slotted (Iteration 2), triple slotted (Iteration 3), and optimized fractal slot (Iteration 4) are studied for ci...

In this paper, a new compact multiband patch microstrip antenna design is presented as a candidate for use in modern multi-functions communication systems. The proposed antenna design is fractally generated using Koch fractal curve geometry applied to the conventional square microstrip patch antenna. Antenna structures resulting from the successive iterations in the proposed fractal generation ...

Fractal array antennas are multiband arrays having ultra wide band and space filling facility. But Side lobe levels and large number of antenna elements are the major designing challenges of these arrays. In this paper, design and analysis of octagonal fractal array antenna is investigated with Morse-Thue fractal density tapering technique (MTFDT). Due to the proposed technique, a remarkable im...

The development of communication engineering with integration technology demands size reduction of low frequency antennas as an important design perspective. In this work, a microstrip patch antenna with Koch shaped fractal slots implemented with a foam substrate (εr = 1.02) is shown to bring a size reduction of about 84 % compared to an ordinary microstrip patch antenna for the same resonant f...

This work presents a new planar multiband antenna based on fractal geometry. This structure is optimized and validated into simulation by using CST-MW Studio. To feed this antenna we have used a CPW line which makes it easy to be incorporated with integrated circuits. The simulation results presents a good matching input impedance and radiation pattern in the GSM band at 900 MHz and ISM band at...
