In this paper, a new miniaturized ultra-wideband bandpass filter is simulated. The structure of the new ultra-wideband bandpass filter is constructed using stepped-impedance resonator. The input admittance of the proposed filter is calculated and compared with the conventional structure. The frequency response of the filter is simulated by an EM simulator tool. The parameters of the proposed fi...
A novel compact microstrip-fed planar monopole antenna with quad-notched bands is presented. The proposed antenna is based on one rectangular-stepped-patch. To achieve the higher resonance over the 12GHz, one lateral L-shaped structure is embedded in the ground. By inserting four U-shaped slots in the radiation patch, quad band-notched properties in the WiMAX (3.3–3.6GHz), INSAT (4.5–4.8 GHz), ...
A compact rectangular printed antenna with dual band-notches is proposed for ultra-wideband (UWB) applications. The dual band-notch characteristics have been realized by etching one C-shaped parasitic element and rectangular split ring resonator above the ground plane. The proposed antenna can achieves a wide bandwidth from 2.9-11 GHz with the dual notched bands centred at 5.25 GHz and 5.8 GHz....
UWB antenna with dual notched characteristics fed by microstrip transmission line is presented in this paper. The tapered connection between the rectangular patch and the feed line is used to produce a good impedance matching from 2.3 to 11.5 GHz. A dual band frequency notches are achieved using UDGS loaded with lumped capacitors. The first notch frequency band is achieved using DGS to reduce t...
A compact UWB monopole band-notched antenna with simple structure and small size is proposed and studied in this article. The size of the antenna is 33 3 29.6 3 1.6 mm. The proposed antenna has an impedance bandwidth (VSWR< 2) at 3.1–10 GHz, except the bandwidth at 3.3–3.7 GHz and 5.15–5.82 GHz for WLAN and WiMAX application. A notch in the ground plane is used to obtain a frequency band-notche...
