“…The advantage of multiband antenna is their ability to integrate multiple frequency bands in a single antenna which makes the design and operation more complex than single and dual band antennas. From literature [2][3], the Fractal antenna arrays like Kotch array, Sierpinski array are also used to achieve the multiband operations. But, the Fractal antennas increase the design complexity.…”

Multiband phased array antennas are required for today’s multi-function communication applications. Generally Microstrip antenna arrays like Kotch array, Sierpinski array are used, but in some circuits where space is limited, arrays are not used. Therefore, to achieve the multiband operation with limited space, an antenna is designed with E-shaped in combination with split ring resonator to achieve the multiband operation. The simulation and experimental results show that the proposed antenna operates at four different frequencies, 1.8GHz, 3.6GHz, 4.53GHz and 5.73GHz, which can be used for different wireless applications like GSM 1800 (1.71– 1.78 GHz), WiMAX (3.4-3.69GHz) -IEEE 802.16 standards, Wi-Fi/WLAN (5.15-5.82 GHz). All the simulation results like resonant frequency, return loss, radiation patterns and fabricated antenna measured result is presented in this paper. The antenna is simulated using CST 2014 software.

“…To surmount these drawbacks and with the increasing demand of multiband antennas, fractal geometry is a good option. Fractal antennas present two benefits [10, 11]. First, these antennas have a geometric specificity that allows them to resonate over several frequencies while possibly keeping the same electromagnetic characteristics, which is known by the self-similarity or similarity of geometric shape at different scales.…”

Vehicle-to-everything communications (V2X), whose main objective is to improve security and efficiency, are provided by ad hoc vehicle networks that allow communication between vehicles. In the current study, a hexagonal microstrip patch antenna has been developed to cover the navigational frequencies, WiMAX at 3.7 GHz and DSRC/IEEE802.11p at 5.9 GHz to meet the demands of various vehicular applications. The antenna design is based on Cantor fractal slot, partial ground plane, and inset feed which is directly fed through the microstrip line. The proposed antenna shields the frequency band from 3.22 to 6.5 GHz with VSWR $\lt$ 2 within all the frequency bands. The presented antenna can resonate well in the 5.85–5.95 GHz band assigned for DSRC/IEEE802.11p and 3.7 GHz assigned for LTE/V2X. Simulated antenna gain varies from 3.06 to 5.25 dB within the operated frequency range providing an omnidirectional simulated radiation pattern in the most azimuth plane. To prove the validity of the simulation results, the chosen antenna structure has been fabricated and tested using a vector network analyzer MS2630. The measurement shows good results, which make the antenna suitable for wireless applications of interest.

“…To translate into its electromagnetic behavior this popular antenna used the self-similarity properties of fractal shape. The classic Sierpinski gasket generated by Pascal triangle is a popular antenna using the self-similarity property of fractals [1][2][3][4]. By altering the radiating strip or ground flat and by utilizing dissimilar shapes, multiple band resonating modes can be achieved [18].…”

An Electric Ring Resonator (ERR) loaded Sierpinski Square Gasket Fractal (SSGF) antenna for multiple frequency band application is proposed, fabricated, and measured. The CPW-fed antenna consists of a Multi-mode Electric Ring Resonator (MERR) which is fixed on reverse side of the substrate and iterated Sierpinski gasket fractal derived from a square patch which is stamped on top of an FR4. Multi-bands can be obtained by placing a single multi-mode ERR beneath the CPW structure of the antenna. Each resonating frequency band can be easily tuned by properly changing the dimensions of the ERR structure. Instead of ERR's quasi-lumped capacitance, reconfigurability of the low, middle, and high frequency bands can be achieved by using a pair of Digital Variable Capacitors (DVCs) inserted into the middle of the ERR's rings corresponding to the chosen mode. The bandwidth is enhanced using four iterations of square radiating patch, modified feed line, and multi-mode electric ring resonator-loaded ground plane. More specifically, the impedance matching of the CPW fed antenna is improved by introducing transitions between the microstrip feed line and the Sierpinski square gasket. The numerical results show that the proposed antenna has good impedance bandwidth and radiation characteristics in the operating bands at 3.08/5.81/8.02/12.13/15.56 GHz which cover the frequency spectrum of WiMAX, WiFi/WLAN(IEEE 802.11a), IEEE 802.16e, X-band uplink, S/C/X/Ku and K band with return loss of better than 10 dB.
