In this rapid changing world in wireless communication, dual or multiband antenna has been playing a key role for wireless service requirements. Wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) have been widely applied in mobile devices such as handheld computers and smart phones. These two techniques have been widely considered as a cost-effective,...

This paper describes a compact triple-band monopole antenna based on Open Complementary Split Ring Resonators (OCSRRs) for Wireless Local Area Network (WLAN) and Worldwide interoperability Microwave Access (WiMAX) applications. The monopole antenna with engraved ground plane is used to cover WLAN frequencies (2.67GHz and 5.47GHz). The resonant frequency of WiMAX (3.43GHz) is achieved by introdu...

A digital RF receiver front-end employing a DT filter is proposed for application to m-WiMAX & The SAW-less receiver architecture, where the large out-of-band interferer can be rejected selectively by using a scalable frequency response property of FIR filter. In addition to the flexibility of the DT filter, the new non-decimation finite impulse response (NDF) filter can be cascaded to a conven...

Worldwide interoperability for Microwave Access (WiMAX) is a Broad Band Wireless Access (BWA) technology. It provides high data rates and multimedia services. It also supports Quality of Services (QoS) for various types of application. When large number of users use these application, the OFDMA is used to divide the channel into several subchannels and those subchannel can be provided for diffe...

A novel compact size ultrawide band planar antenna with notched characteristics is present. The rejection characteristic achieved by loading a pair of metamaterial inspired rectangular split ring resonator (SRR) near the feed line and etching SRR slots on radiating patch. simulated measured results reveal that proposed exhibits impedance bandwidth over (UWB) frequency range from 3.1 to 14 GHz v...

A compact printed wide-slot (PWS) antenna is proposed for UWB applications. The proposed UWB-PWS antenna basically consists of a stepped microstrip feed-line with a rectangular patch stub and a rectangular wide-slot element at the aperture. Additional parasitic split-ring elements are placed along the patch stub to achieve notch-band characteristics. As the proposed antenna in absence of the ri...

A miniature single-layer CPW-fed monopole antenna with triple-band operation for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications is presented. The proposed antenna, comprising a planar rectangular patch element embedded with dual U-shaped slot, is capable of generating three distinct operating bands, 2.37–2.53, 3.34– 3.82, and 4.23–6.8...
