In this a compact modified U-Shaped design with coplanar waveguide (CPW) fed triple band notched antenna was proposed. The proposed antenna, with compact size of 24×33 mm 2 , yields an impedance bandwidth of 120%(S11<-10dB criteria). The notched bands are realized by introducing two different types of slots. Two C-shaped half-wavelength slots are etched on the radiating patch to obtain two notched bands in 3.3-3.7 GHz for WiMAX and 7-7.75 GHz for downlink of X-band satellite communication systems. In order to minimize the mutual coupling between the band-notched structures, the middle-notched band in 5.5-5.8 GHz for WLAN is achieved by using a U-slot defected ground structure. The parametric study is carried out to understand the mutual coupling. The performance of the antenna is evaluated in terms of return loss(S11), VSWR and Radiation Patterns.

“…UWB covers the frequency band ranges from 3.1-10.6 GHz with 7.5 GHz bandwidth, there are several advantages of this very large bandwidth as it consumes less power, have low implementation cost, with high data rate and time-resolution, also have the capability of obstacle penetration [2]. Such advantages widen the number of prominent applications in the field of communications such as wireless local area network (WLAN), wireless body area network (WBAN), WiMAX, wireless personal area network (WPAN), also in the field of radar like ground penetrating radars (GPR), imaging and positioning [3].…”

Abstract. The aim of this paper is to present a monostatic arc-shaped ultra-wideband (UWB) printed monopole antenna system with 3-16 GHz frequency bandwidth suitable for through-wall detection. Ground penetrating radar (GPR) technique is used for detection with the gain of 6.2 dB achieved for the proposed antenna using defected ground structure (DGS) method. To serve the purpose, a simulation experiment of through-wall detection model is constructed which consists of a monostatic antenna act as transmitter and receiver, concrete wall and human skin model. The time domain reflection of obtained result is then analysed for target detection.

“…An enhanced bandwidth triple band-notched UWB antenna is reported in [9] which also contains a rectangular patch with two bevels, by inserting two round-shaped slots of half wavelength in the radiating patch and by etching out a pair of C-shaped slots in the ground plane. Fractal Koch and T-shaped stub for a triple-notch UWB monopole antenna is presented [10], centered at 2.00 GHz, 3.50 GHz and 5.50 GHz, respectively. Triple notched band resonators in a single design are fabricated [11] by inserting a C-shape slot at main radiator, complimentary SRR (CSRR) at ground plane and an inverted U-shape slot at the center of the patch, resulting in narrow band rejection of triple-notched band.…”

Abstract-In this paper, a CPW-fed circular patch UWB-extended bandwidth antenna is proposed which is fabricated and characterized on silicon.The proposed antenna covers fractional bandwidth of 132.08% with high rejection triple band-notch characteristics [WiMAX(3.30 GHz-3.80 GHz)/WLAN(IEEE802.11a/h/j/n 5.15 GHz)/X-band downlink satellite communication system (7.25 GHz-7.75 GHz)]. Gain and efficiency of the proposed antenna in the entire bandwidth vary between 3.96 dBi-10.98 dBi and 84%-95%, respectively. Also, group delay in the entire operating band is ≤ 1.0 ns. Furthermore, the proposed antenna exhibits good dipole like radiation pattern in E-plane and omnidirectional pattern in H-plane with small dimension of 20 × 20 × 0.5 mm 3 .
