CPW-fed slotted CANTOR Set fractal antenna for WiMAX and WLAN applications

Abstract

othmane benhmammouch 2 , ahmed oulad said 3 , abdelhakim el ouadih 3 and marouane bouchouirbat 4 This paper presents the behavior of three iterations of a coplanar waveguide fed CANTOR Set fractal antenna. This kind of antennas allows having a broadband behavior and important gains. Also, the setup of slots allows having more lower resonant frequencies and therefore designing miniaturized antennas with good performances. The proposed antennas are suitable for 2.5/3.3/5/5.5 GHz worldwide interoperability for microwave access and for 2.4-2.5/4.9-5.9 GHz wireless local area networks applications. The simulations were performed in FEKO 6.3. The measurements were performed with Vector Network Analyzer HP 8719C.

Design of Microstrip Sierpinski Carpet Antenna Using a Circular Pattern with Improved Performance

“…The antenna is than fabricated and tested using Vector Network Analyzer (VNA Master, Anritsu MS2026C) to validate the simulated results in the band [1][2][3][4][5]. We confirm with measurements that resonance frequencies become lower when the iteration number increases.…”

“…A good design of the antenna can thus improve overall system performance. As the demand increases day by day to multi-band antennas, Thus, a major issue in multiband communications concerns small or very small terminal dimensions, intended for short radio ranges and in association with sensors or networks for information transfer in a domestic, multimedia or professional context [1][2][3]. Low consumption, ease of integration, and above all cost are essential aspects that are not very compatible with performance, these antennas also have wide applications in long range of wireless systems.…”

Compact Broadband Antenna with Vicsek Fractal Slots for WLAN and WiMAX Applications

“…[21], the antenna had a complex structure printed in Taconic RF-35, it achieved a broadband, and it did not cover all the bands of WLAN and WiMAX. The suggested broadband antenna has various advantages over previously reported antennas [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] in terms of size, impedance bandwidth and gain, as shown by the comparison.…”

“…Similarly, in [8], a Hilbert fractal slot was inserted in an octagonal radiator to operate in WLAN and WiMAX applications, and it offered a dual band at 2.48 and 5.68 GHz with a bandwidth of about 0.7 and 3.55 GHz, respectively. A novel CPW rectangular antenna with a cantor fractal slot was developed in [9]; it shielded two bands of about 1 and 1.7 GHz at resonant frequencies 3 and 5.1 GHz. Likewise, in [10], a compact antenna for UWB notched applications was developed; it covered a bandwidth from 3.1 to 10.6 GHz, with a rejected band from 2.4 to 2.484 GHz, for WLAN applications.…”

Broadband microstrip antennas with Cantor set fractal slots for vehicular communications

“…Cantor dust described by mathematician Georg Cantor in 1872 is probably the oldest known fractal and the easiest to create [24–26]. The construction of this structure is based on a straight line segment from which the central third is removed.…”
