“…Super wideband (SWB) antennas are the antennas which support more than decade bandwidth (10 : 1 or more) at S 11 ≤ −10 dB [1]. Different techniques have been utilized in designing these types of planar, low profile compact antennas which can support SWB operation [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

In this paper a staircase fractal curve is applied on a microstrip line fed truncated corner square patch antenna to achieve Super Wide Band (SWB) operation. The proposed antenna exhibits an impedance bandwidth from 0.1 GHz to 30 GHz with a ratio impedance bandwidth of 300 : 1 for S 11 ≤ −10 dB. The bandwidth enhancement of the proposed antenna structure due to the fractal curve is shown in a step by step manner. The Bandwidth Dimension Ratio (BDR) of the proposed antenna design is obtained as 496675. Relatively stable omnidirectional radiation pattern and satisfactory value of gain are obtained over the operation band. Time domain analysis has also been performed to check the applicability of the proposed design as SWB antenna.

“…Antennas with ratio bandwidth greater than or equal to 10:1 are treated as SWB antennas [2], [3]. Some printed SWB antenna structures [1], [3][4][5][6][7][8][9][10][11][12][13][14] using fractal monopoles with defected ground plane for enhanced impedance bandwidth and compact size are reported in the open literature.

This article presents a super wideband (SWB) circular-shaped fourth iterative fractal antenna loaded with concentric hexagonal slots. A tapered microstrip feed and a partial ground plane is used. It has a total size of 40 × 27 × 1.6 mm3. Numerical results of the antenna show that it provides a bandwidth from 1.43 GHz to more than 40 GHz (percentage bandwidth greater than 186%) with a bandwidth ratio of approximately greater than 28:1 for S11 < -10 dB. A prototype of the proposed antenna has been fabricated and its performances are measured up to 15 GHz. A good agreement is achieved between the numerical and experimental reflection coefficient, VSWR and input impedance. Measured radiation patterns at different frequencies and simulated peak gain are presented and discussed. It has the advantages of super wide bandwidth and compact size. The developed antenna is suitable for various wireless communications such as GPS, GSM, UMTS, ISM and UWB.

A compact circular fractal antenna element loaded with a central pentagonal slot is presented in this paper. This structure consists of a fourth iterative radiator fed by a partially tapered feed line and CPW defected ground plane. A superwide impedance bandwidth of 3.45-52.17 GHz ($175% fractional bandwidth) is achieved. Two multiple input multiple output (MIMO) configurations are also designed and analyzed by using this antenna element. For spatial and pattern diversity configurations, the impedance bandwidth of 3.45-52.2 and 3.1-52.2 GHz are achieved, respectively. The optimized footprints of antenna element, spatial diversity configuration, and pattern diversity configurations are 28 Â 24, 28 Â 53, and 45 Â 48 mm 2 , respectively. The isolation for both MIMO configurations is more than 20 dB in maximum portion of the operating bandwidth. Desirable radiation and diversity performance characteristics are achieved for antenna element and MIMO configurations. The wide bandwidth, compact dimensions along with good radiation, and diversity performance characteristics make the proposed antenna configurations suitable for integration in superwideband wireless communication systems. A good agreement between the experimental and simulation results is observed.coplanar waveguide feeding, defective ground structure, fractal antenna, MIMO applications, superwideband applications, tapered feed line | INTRODUCTIONAfter the allocation of unlicensed frequency spectrum 3.1-10.6 GHz for ultrawideband (UWB) applications by Federal Communication Commission (FCC) in 2002, both academic and industry researchers started making efforts for the integration of UWB technology in wireless communication systems. This integration resulted in secure wireless communication services at high data rates over a wide range of frequencies. With the advancement in technology, the demands for security, data rate and wide bandwidth increased exponentially. These demands required antenna structures which can provide service for both short-range and long-range communication (already covered by UWB spectrum). To fulfill these demands, a new technology, that is, superwideband (SWB) technology, having ratio bandwidth of 10:1 or more is defined. To integrate SWB technology in wireless communication systems, several antenna structures were explored to operate over a wide range of frequencies and can be integrated with compact communication devices. Among the various explored antenna structures, monopole antennas are found be good candidates who can provide
