Performance Analysis of Coaxial Probe Fed Modified Sierpinski–Meander Hybrid Fractal Heptaband Antenna for Future Wireless Communication Networks Yadwinder Kumar 1 • Surinder Singh 2 Ó Springer Science+Business Media New York 2016 Abstract A planar modified Sierpinski–Meander hybrid fractal antenna suitable for future wireless communication networks capable of exhibiting heptaband behavior has been presented in this paper. Proposed radiating structure is obtained by combining a modified Sierpinski gasket and Meander like antenna (for lower frequency) to obtain a hybrid structure exhibiting multiband behavior. Difficulty of designing a complex fractal structure has been eased by using scripting method (*.vbs) in HFSS obtained from IFS and MATLAB. Proposed antenna has partial-defected L-shaped ground structure which helps to obtain higher values of Gain. It has dimensions of 54 9 46 9 1.6 mm 3 and resonates at 2.4, 4.437, 5.38, 7.01, 7.60, 8.41 and 9.09 GHz which covers useful applications like Bluetooth, WLAN, Wi-Fi, ISM, RFID, 4G/LTE, radiolocation and mobile/fixed satellite service. Prototype of the proposed structure is fabricated on FR4 substrate and tested. Measured results are analyzed and compared which are in good agreement with the sim- ulated ones.
