Self Cite

A compact (35 × 30 × 0.8 mm3) co‐planar waveguide (CPW)‐fed circular monopole ultra‐wideband (UWB) antenna with improved impedance band is proposed in this article. A frequency band from 3.1 to more than 20 GHz is achieved by bending the upper edges of co‐planar ground plane. Antenna parameters are studied by simulation and then validated by experimental measurement. The proposed antenna provides monopole‐like radiation pattern with high radiation efficiency of more than 80% and flat gain variation between 2 and 5 dBi. The antenna also exhibits consistency in group delay variation and linearity in the transfer function response. A good agreement is found in between simulated and measured results of the proposed design. The proposed antenna performance is compared with previously reported similar antennas.

“…4 Several techniques have been used to create a UWB range such as half-groundplan antennas, coplanar wave guide (CPW) or slot antennas. 5 Various narrow-band systems have been proposed in the literature for WiMAX (wireless interoperatibility for microwave access) with frequency band (3.2-3.8 GHz), 6 C-band for satellite applications (3.7-4.2 GHz), 6 and WLAN (wireless local area network) at frequency band (5.15-5.85 GHz) 7 and created various problems with UWB systems, among of these troubles the electromagnetic interference (EMI) problem. 8 This interference can be removed by using traditional filters (radio frequency filtering), but this operation causes more problems, because the filters occupy a large space when they are integrated with other microwave circuits.…”

In this paper, a compact UWB (ultra‐wideband) antenna with three C‐shaped slots for notched band characteristics is presented. The proposed antenna covers a bandwidth between 2.95 GHz and 12 GHz. Three different sizes of C‐shaped slot are integrated in the radiating element to remove three frequency bands at WiMAX (3.2‐3.8 GHz), C‐band (3.7‐4.2 GHz), and WLAN (5.15‐5.85 GHz). The antenna has a compact size (30 × 30 mm2). The simulated results show good and acceptable agreement with measurement results in terms of S‐parameters and radiation patterns.

“…The most used shapes are circular, triangular and square . Besides, more complicated shapes have been used such as fractal, umbrella shaped, leaf‐shaped, and Ψ‐shaped . However, the developed antenna designs present the disadvantage of relatively large size and limited bandwidth.…”

In this paper, a compact superformula ultra‐wideband (UWB) monopole antenna with dual band notches is proposed. The developed structure achieves UWB performance as well as a compact size of 20 × 26 × 1.62 mm3. Furthermore, to avoid interferences with WiMAX and satellite communication systems, dual notched band is obtained by engraving two co‐directional triangular split ring defects on the radiating element. The simulated and measured results show that the proposed antenna has an impedance bandwidth extending from 3.05 to 20 GHz with dual notched bands at [5.15‐5.68 GHz], and [7.15‐7.65 GHz] used in WiMAX and satellite communication, respectively. The proposed design realizes omnidirectional radiation pattern in H‐plane, and a dipole‐like pattern in E‐plane. The antenna exhibits an acceptable gain in the whole UWB range except at notched bands.
