Triangular Shape

A proximity-fed complementary Sierpinski gasket fractal with equilateral triangular shape resonator in multilayer structure to achieve dual-band behavior for WiMAX and WLAN applications has been proposed. An electromagnetic coupled stacked structure of two different patches operating at two frequencies (3.5 GHz WiMAX and 5.8 GHz wireless LAN) has been designed for dual-band wireless applications. Proposed antenna was simulated using CST Microwave Studio based on the finite integration technique (FIT) with perfect boundary approximation (PBA). Finally, the proposed antenna was fabricated and some performance parameters were measured to validate against simulation results. The design procedures and employed tuning techniques to achieve the desired performance are presented.

There is highly demand of antenna with these characteristics: compact size, low profile and multiband or broadband but at the same time have to maintain antenna parameters. This paper focuses on design of Sierpinski Gasket Fractal Antenna (SGFA) with slits for multiband application.Two methods are applied to this antenna to improve its performance. The first method is by adding two slits on the fractal antenna. The second method is by increasing the number of iterations of the fractal antenna. These methods can improve the return loss and gain of the antenna. The simulation of the designed antenna is carried out by using Computer Simulation Technology (CST) software. The simulated return loss of SGFA with slit is about -20.1 dB and -11.64 dB compare with SGFA without slit -19.25 dB and -12.27 dB at 2.4 GHZ and 5 GHz. While, the gain also increase when slit is added to SGFA. The simulated and measured of antenna parameter is well compared

Wireless communication systems require antennas of multiband support,small design dimensions and higher gain. To provide size reduction and better impedance matching, geometrical interpreted fractal antenna is suitable. This allows the antenna to operate at different frequencies. To rise performances with respect to bandwidth, gain and multiband resonance, an array can fulfil the requirements. This paper shows the design and simulation of the Sierpinski Gasket array for multiband applications (4GHz to 8GHz, 8GHz to 12GHz) up to 4th iteration. The fractal geometry for patch antenna is selected due to low cross polarization radiation and ease of fabrication. Sierpinski gasket is known by the name, Sierpinski triangle having triangular slots using mid-point geometry of the triangle. This array makes use of micro strip feed where FR4 epoxy is used as the dielectric substrate. A low profile dielectric is used to get the radiation in maximum amount. This antenna finds its uses in satellite communications and transmissions,Wi-Fi. The simulation is carried out by using High Frequency Structure Simulator HFSS V13 software for the proposed antenna.
