The Federal Communications Commission (FCC) permitted the public to use UWB bandwidth for commercial purposes after 2002. Furthermore, the FCC approved the usage of the UWB spectrum, which is allocated between 3.1-10.6 GHz in the United States [2]. The low spectral density of UWB is responsible for short range of communication. This function, however, demands high-gain antennas with relatively stable radiation characteristics [3]. Planar antennas, primarily monopoles, are used in UWB electrical devices [4,5] due to its compact size, low profile, and low cost, as well as its ultra-wide impedance bandwidth. Moreover, when these antennas are placed near metallic surfaces, they can cause severe impedance mismatch. Low-profile antennas also transmit limited frequency signals with low gain and poor directivity [6,7]. However, the cost and size of the UWB antennas increases with discreet filters [8]. Frequencies from 5.2-5.8 GHz were notched by etching an omega type slot on the surface of the antenna in [9]. Similarly, in [10], U- and inverted U-shaped slots were embedded in printed monopoles to stop multiple frequencies. A curved shaped slot is introduced in [11] to achieve notching features in WiMAX and WLAN bands. To attain notching characteristics in 5.10-5.94 GHz, an S-shaped slot is applied in the feedline of the monopole antenna in [12]. Split ring resonators can act both as a band stop and band pass filters for different frequencies [13]. In [14], uplink and downlink satellite frequency bands were rejected by introducing a single SRR slot in the patch of the antenna. A WLAN band is rejected by inserting split ring resonators in [15]. Three different frequencies were notched in [16] by embedding multiple split rings near the feedline of the antenna model. Notching was achieved by using SRR in [17]. Tri-notching using frequency-selective surface (FSS) of an ultra-wideband antenna with gain augmentation was reported in [18]. Another compact-sized UWB planar antenna using truncated ground plane was presented in [19]. The antenna covers large bandwidth, but the size was still large, compared to our design. A broadband overleaf-shaped antenna using beam tilt characteristics is presented in [20]. The reported size of the antenna is large, and small bandwidth is achieved, as shown in Table 1. Another Vivaldi antenna resonative over a wide frequency range is reported in [21]. The antenna is antipodal, and the miniaturization was achieved by using exponential strip arms technique. In this research article, a simple CPW based an ultra-wideband antenna having impedance bandwidth ranging from 3 GHz to 11 GHz (8 GHz) for wireless communication networks is presented.
