a newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (uwb) applications. the two band notches of this coplanar waveguide (cpw) fed antenna are achieved by an m-shaped slot (mss) embedded in the radiating element and a c-shaped strip(css) close to ground plane, therefore two very narrow rejected properties in the wireless loc...

Due to the integration of different wireless applications at different bands on a single device, multi-band microstrip patch antenna is the best solution keeping the overall size of the device small. In the present work, a metamaterial-inspired antenna is proposed for WiMAX/WLAN applications. Design studies, parametric analysis, simulation results along with measurements for a L-shape slotted g...

Due to the size constraint, antennas with compact are required that can support multibands single radiating element. Dielectric resonator antenna (DRA) multiple modes good efficiency and gain using In this paper, a quad-band DRA is proposed for WLAN/WiMAX bands CPW feed. Out of four bands, WLAN (2.37-2.55) GHz, (5.15-5.35) (5.6-5.83) GHz achieved by excitation fundamental higher-order whereas W...

The main objectives of this paper is to examine the performance of the wireless broadband infrastructures and their support for Triple Play services under different separated scenarios by using OPNET Modeler 14.5. This simulation network uses several features to study the performances of WiMax on Triple Play services, 3.5GHz band is chosen in our studies because it is widely used band all over ...

This study considers the different UWB antenna designs with band notch characteristics. Different antennas designs to reject interference from WLAN, WiMAX, DSRC, and HIPERLAN/2A are considered and listed in table. Index Terms – UWB, WLAN, WiMAX, HIPERLAN/2A.

A novel planar antenna with WiMAX and WLAN bandnotched characteristics is presented for ultra-wideband (UWB) applications. The UWB antenna consists of a staircase-shaped radiating element, a microstrip feedline and a modified ground plane. To realize WiMAX band-notched characteristic, a pair of hook-shaped slots is etched on the radiating element. Two folded stubs extending from the ground plan...

A small triple-band 2.7 GHz, 3.2 GHz and 5.3 GHz compact microstrip patch antenna with two Ushaped slots and a small ground plane is presented. It has been developed to be used in future WiMAX technology. The required bandwidths are fulfilled the WiMAX technology 4.8 %, 3 % and 2.5 % respectively. The return loss for the triple band are -18.5 dB, -14.5 dB and -19 respectively.

The radio access technologies also presents the Coexistence issues between UWB and WiMAX systems at 3.5GHz frequency band which has been recently attained more attention. For investigating the potential interference of ultra-wideband (UWB) on a WiMAX system, an analysis method based on the physical layer modeling is presented. Multi-band orthogonal frequency division multiplex (MB-OFDM) UWB and...

Multi band H shaped MSA is presented here. This antenna is suitable for DCS, WiMAX and WLAN application. FR-4 epoxy substrate is used on which H shaped slot is cut by etching technique. This structure radiates for DCS (1.71-1.88) GHz, low band WiMAX (2.50-2.69) GHz and WLAN (5.15-5.35) GHz. The return loss obtained at 1.8268 GHz, 2.6352 GHz and 5.2840 GHz are -38.62 dB, -50.62 dB and -19.48 dB ...
