In this paper, a stage wise realization of compact Bluetooth — UWB dual-band diversity antenna with WiMAX and WLAN band-notch characteristics is presented. The proposed structure consists of two co-planar semicircular dual band-notch monopole antennas, mounted with planar spiral. Individual antenna configuration provides an impedance bandwidth (VSWR < 2) for dualband i.e., both Bluetooth and UW...

Worldwide Interoperability for Microwave Access (WiMAX) and other broadband wireless technologies are associated with a variety of frequency spectrums. It is essential to identify optimal frequency spectrum for implementing a technologically sturdy and strong WiMAX network. This paper compares different frequency spectrums centering various parameters like path loss, interference factors, cover...

WiMAX (Worldwide Interoperability for Microwave Access) is the emerging wireless technology standard of the near future, which enables high speed packet data access. To anticipate the future demands on WiMAX technology, we proposed an ADPLL (all-digital phase locked loop) solution for the WiMAX system. The developed ADPLL system has targeted frequencies from 2.3 GHz to 2.7 GHz and from 3.3 GHz ...

This paper presents the numerical simulation of double U-slots microstrip patch antenna for WiMAX application. The proposed antenna is feed by the Transmission line. The total area occupies by the antenna 40mmx47mm. In this design two slots and one bridge elements have been applied to generate the three frequencies bands 2.44GHz, 3.26GHz and 5.38GHz respectively. In addition, the antenna has ac...

In this paper a monopole antenna for WLAN and WiMAX frequencies is proposed. The given antenna is composed of a rectangular patch monopole antenna having an E-shaped slot with two backward slits on the substrate and a defected ground plane. The antenna exhibits single band, which creates an impedance bandwidth of 2 GHz for the working band of 4-6 GHz. The various characteristic parameters like ...

A rectangular microstrip antenna for dual band and tri-band is developed using a parasitic technique. Single rectangular microstrip is splitted into multiple resonators along the width and gap coupled to non-radiating edges. The proposed structure gives sufficient separation between the operating frequencies increasing bandwidth for dual band and tri-band. It covers the frequency range from 190...

The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a fractal circular monopole patch antenna. The other important property that is, Space-filling property which actually determines the reduction in the size of the antenna. This property adds more electrical length in less volume which reduces the size of ...

Wired WLAN (Wireless Local Area Network) technology emerged as the most widely used network. is suitable for those who need internet. By using will be found various advantages its users. Likewise with WiMAX (Worldwide Interoperability Microwave Access) wireless technology, basically has a function similar to WLAN, but certain small differences. can cover one local area, in contrast which metrop...
