“…Thus, it is desirable to design a UWB antenna with multiple band-notched characteristics to avoid the potential interference. In the published literatures, there have been some reports on the UWB antennas with band-notched characteristics [7][8][9][10][11][12][13][14][15]. However, most of these antennas are designed to generate only one notched frequency band so that just one narrow band of disturbance can be eliminated.…”

Abstract-A novel self-similar antenna for band-notched ultrawideband (UWB) applications is proposed. The UWB performance is obtained by introducing a quasi-trapezoidal radiating patch and a self-similar ground plane. By etching two similar slots on the radiating patch, band-notched characteristic can be obtained. The measured results show that the antenna covers the band of UWB from 2.6 to 12.8 GHz excluding the rejected bands from 3.3 to 3.6 GHz and from 4.8 to 6.0 GHz. In addition, the antenna exhibits nearly omni-directional radiation patterns and stable gains over the operating bands.

“…Therefore, the UWB antenna with rejected characteristic is required. In the present literatures, the most popular methods to generate the frequency band-notch function are embedding slots [6][7][8], using defected ground structure (DGS) [9][10][11], or employing the above two methods simultaneously [12][13][14]. Unfortunately, these designs can only obtain one rejected band with the complicated structures.…”

Abstract-A compact microstrip-fed ultra-wideband (UWB) planar monopole antenna with dual band rejected characteristic is presented in this paper. By etching two identical square complementary split ring resonators (CSRRs) in the radiation patch, dual band rejections in the WiMAX and WLAN bands are achieved. The proposed antenna, with the size of 30×34 mm 2 , has been constructed and tested. And the measured results show that the antenna can operate over the frequency band between 3 and 11 GHz for VSWR < 2 with dual band notches of 3.4-3.6 GHz and 5.1-5.9 GHz. Besides, in the working bands, the antenna shows good omnidirectional radiation patterns in the H-plane and monopole-like radiation patterns in the E-plane and has good time-domain characteristic as well.

“…In [26], a directional UWB array has been realized by using four pairs of leaf-shaped bowtie elements and a flat aluminium plate as a reflector. Recently, various planar monopoles have been reported [27][28][29][30][31]. In [32], a compact UWB UHF array antenna has been developed for through wall radar by using the printed elliptical monopole antenna.…”

Abstract-A compact-size planar antenna with ultra-wideband (UWB) bandwidth and directional patterns is presented. The antenna can be fabricated on a printed circuit board (PCB). On one side of the PCB, it has a circular patch, and on the other side it has a slot-embedded ground plane with a fork-shaped feeding stub in the slot. Directional radiation is achieved by using a reflector below the antenna. To reduce the thickness of the antenna, a new low-profile antenna configuration is proposed. Three types of directional UWB antennas are analyzed. The distance between the antenna and the reflector is 12 mm (0.16λ 0 , λ 0 is the free space wavelength at the lowest frequency). In order to validate the design, a prototype is also fabricated and measured. Measured results agree well with the simulated ones. The measured results confirm that the proposed antenna features a reflection coefficient below −10 dB over the UWB range from 4.2 GHz to 8.5 GHz, a maximum gain around 9 dBi, a front-to-back ratio over 17 dB and pulse fidelity higher than 90% in the time domain. Thus it is promising for see-through-wall imaging applications.
