Abstract: The Research work proposes MPA with KochKoch and KochMinkowski slots and hybrid fractal antenna along with existing fractal shapes. newlineInset feed used in Sierpinski Circular Fractal Antenna not only improves the Gain and number of frequency bands but also miniaturize the antenna. newline Three iterations have been applied in the Sierpinski Carpet rectangular geometry and it operates at five unique frequencies in all iterations. newline Designed Giuseppe Peano depicts miniaturization almost 269 percent of the original size. newline With inset feed, number of frequency bands has been improved in Hexagonal Meander antenna. newlineThree iterations have been applied in MPA with Minkowski geometry and Multiband behavior of antenna is reported. newline Minkowki and Sierpinski Carpet geometries fused together to design HFA named as Antenna1 and Antenna2. The Simulated Antenna1 and Antenna2 operates 4 and 5 frequencies. Fabricated Antenna1 and Antenna2 operates at 3 and 4 frequencies. To attain the desired frequency, U shaped ground plane is introduced in Antenna2 named as modified HFA which resonates at 3 frequencies and also exhibits desired frequency. newlineMPA with hybrid fractal slot KochMinkowski and KochKoch has designed using DGS for wideband applications. The length of DGS is decreased from 10 mm to 7 mm with step size 0.5 mm to optimize antenna parameters. Ground plane length 8 mm reports best results. The MPA with KochMinkowski slot depicts 2260 MHz bandwidth 6.1dB gain and 2 resonant frequencies whereas KochKoch slot reports 2440 GHz bandwidth, 5.62 dB gain, and 2 resonant frequencies. The measured bandwidth for KochMinkowski and KochKoch slot is 3326 MHz and 3237 MHz. To include the designed frequency, the L shaped ground plane has been introduced and noticed that designed frequency has been achieved in the frequency range 3.05 to 3.35. newlineThe close agreement has been observed in between simulated and measured results of proposed antennas. The proposed antennas are useful for Bluetooth, WiMax, C Band, WLAN, Point to Point high speed Comm.
