“…The small square monopole antenna has been designed for UWB applications, along with inverted T-shaped slot and conductorground plane to improve the impedance bandwidth. The WLAN Frequency band notch is obtained by rotated C-shaped strip around the inverted T-shaped conductor back plane [6] and U-shape strip is parasitically attached to the feed layer [7]. In [8], a planer slot antenna was proposed for UWB application along with dual-band-notch characteristics.…”

A micro strip-fed printed, modified hexagonal slot ultra wideband antenna with a band notch function is presented as well as investigated in this paper. The basic antenna comprises a U-shape radiating patch on one side of the substrate and ground plane with modified hexagonal slot on the other side of the substrate. Proper alignment and use of a modified hexagonal slot gives additional resonances and much wider impedance bandwidth is obtained. To create a notched band for WiMAX, symmetrical L-shape parasitic stubs are embedded in the upper edge of the modified hexagonal slot of the ground plane. The proposed antenna operates over the frequency band from 2.71 GHz to 11.73 GHz with a band rejection from 3.27-4 GHz (for WiMAX).The proposed antenna is fabricated on a FR-4 substrate having a dielectric constant of 4.4 with an overall size of 28 x 28 x 1.6mm 3 . Parametric studies have been conducted by changing length, width and thickness of symmetrical L-shape parasitic stubs. Simulated results are in good agreement with measured results. Designed antenna exhibits good radiation, efficiency greater than 80% within the entire ultra wideband except for WiMAX frequency.Index Terms: Modified hexagonal slot antenna, ultra wideband (UWB), U-shape radiating patch, WiMAX.

“…There are also other methods to realize the band-notched property. For example, in [18], a notched band around 5.5 GHz is obtained by embedding a pair of T-shaped stubs inside an elliptical slot in the radiation patch; the complementary split-ring resonator (SRR) is employed near the feed line to generate notched bands in [19]; the antenna in [20] uses a coupled C-shaped parasitic structure to obtain a band-notched function. However, most antennas of the previous works can realize only one or two notched bands.…”

“…By symmetrically placing a pair of the MCLL resonators in the vicinity of the feed line of the UWB antenna, three notched bands with central frequencies at 3.55, 5.5 and 7.8 GHz can be achieved. Moreover, compared with the notch structures mentioned in the antennas above [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], the MCLL resonator has triple resonant frequencies that result in the generation of three notched bands of the UWB antenna. The proposed design is simulated using the ANSYS High Frequency Structure Simulator (HFSS), a commercial 3-D full-wave electromagnetic simulation software.…”

Abstract-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 feed line to achieve triple band-notched characteristics, such as 3.4-3.7 GHz for WiMAX, 5.15-5.825 GHz for WLAN, 7.25-8.395 GHz for X-band satellite communication. The good performance of triple notched bands, stable gain and omnidirectional radiation patterns in the operating bands make the proposed antenna a good candidate for UWB utilization.

“…To eliminate the interfaces antenna filtering technique has become an excellent candidate due to its simplicity, effectiveness, and low cost. Several methods have been proposed for designing UWB antennas that exhibits band-notched functions, including etching of various shapes such as C, L, T, H, U on radiation patch or on ground plane [4][5][6][7]. In this paper, a circular patch antenna that is applicable to UWB systems is proposed.…”

Current antenna research mainly focusses on antennas that are well suited for Ultra Wideband (UWB) applications. Multiple antennas were used to achieve the whole UWB range in the earlier designs, which was not compatible for smaller devices. A novel, compact circular patch antenna for UWB applications is proposed. An inverted T-shape structure is etched in the ground plane along with a C-shaped strip. The proposed antenna is capable of radiating in the entire UWB range with sufficient gain and desired radiation patterns. Antenna exhibits a notch that comes under the X-band. The antenna proposed here is suitable for entire UWB range application and it avoids the interference from X-band which is used for satellite and military applications.
