In this paper, a novel microstrip-fed compact antenna with triple band-notched characteristics is presented for ultrawideband (UWB) applications. The antenna consists of a circular radiating patch, a 50 Ω microstrip feed line, a partially slotted ground plane, and a pair of modified capacitance loaded loop (MCLL) resonators. The novel resonators are symmetrically located in the vicinity of the ...

A compact ultrawideband (UWB) monopole antenna with two U-shaped slots for WLAN and WiMAX dual band-notched functions is proposed and experimentally studied. The proposed antenna with the size of 28mm × 24mm × 1.6mm is excited by a 50Ω microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on th...

In this paper, a microstrip-fed hexagonal shape ultra-wideband (UWB) monopole antenna with triple notched bands is presented. The antenna consists of a microstrip feed line, a regular hexagonal shape radiation patch with a complementary split ring resonator (CSRR) and a pair of inverted T-shaped conductor-backed planes embedded in the antenna backside. Notched bands can be easily controlled by ...

The notched-noise method has been widely used to estimate the shape of the auditory filter. Results obtained using this method may be influenced by combination bands produced by the interaction of components within the upper band of noise in the notched-noise masker. To assess the possible effect of such combination bands, results were compared for two types of masker: A notched noise, as used ...

A novel planar ultra-wideband (UWB) antenna with triple-notched bands using triple-mode stub loaded resonator (SLR) is presented in this paper. The basic UWB antenna consists of a circularshaped radiating element, a 50Ω microstrip feed line, and a partially truncated ground plane. Then, the resonance properties of the SLR are studied. Results reveal that the multiple-mode property of the SLR ca...

An ultra-wideband (UWB) printed monopole antenna with dual band-notched characteristics is proposed. Two spiral electromagnetic-bandgap (EBG) structures placed on the front and back side of the substrate are employed to create two notch bands at 5.2 and 5.8 GHz for the lower and upper bands of the wireless local-area network (WLAN), respectively. The notch-frequency can be tuned, and the band w...

A compact ultra wideband (UWB) monopole antenna with dual band-notched characteristics is presented. The antenna consists a square radiating patch with L shaped slots on the radiation patchand a U shaped slot as the feedline. By cutting two C-shaped slots in the ground plane, additional resonance is excited and hence much wider impedance bandwidth can produced, especially at the higher band, wh...

A compact ultra-wide-band (UWB) band-pass filter (BPF) with dual notch bands is presented using novel defected ground structures (DGS). A couple of triangle-ring resonators with four open-stubs fed by a couple of inter-digital coupled structures is developed to meet the UWB requirement of a uniform 3.1GHz to 10.6GHz full-band transmission response. Dual notch bands are generated for filtering o...
