Novel dual-band WLAN antenna system with integrated band-select filter is designed. This integrated antenna design system provide VSWR 2:1 for both 2.4–2.5 GHz and 4.9–5.85 GHz with omni-directional radio patterns. Based on these features, a novel architecture for a dual-band WLAN radio Front-End in portable devices can be achieved. © 2007 Wiley Periodicals, Inc. Microwave Opt Technol Lett 49: ...

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...

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...

A fourth-degree Substrate Integrated Waveguide (SIW) crossed coupled band pass filter for WLAN band is designed by using a new negative coupling structure. It consists of two U shape microstrip lines on top and bottom planes with via holes at the center of them. This paper investigates the phase characteristics of negative and positive coupling structures and their effects. The design, fabricat...

This paper introduces the design of a dual-band internal F-PIFA (Fractal Planar Inverted F-antenna) as a candidate for use in the dual band WLAN (wireless local area network) MIMO (multi-input multi-output) applications. At first, the 4th iteration Koch’s fractal geometry has been applied to the edges of the conventional rectangular patch structure to design a single compact antenna with a dual...
