A novel multi-band clover leaf-shaped fractal antenna with integrated filtering to reduce higher order harmonics has been proposed. Existing microstrip antennas endure limited gain, narrow impedance bandwidth, and undesired frequency radiations. The proposed is designated operate simultaneously in following operating bands: 3.35–3.6 GHz for WiMAX, 5.156–5.825 WLAN, 5.7–6.4 Intelligent Transport...

In this letter, a tapered slot ultrawide band (UWB) Vivaldi antenna with enhanced gain having band notch characteristics in the WLAN/WiMAX band is presented. In this framework, a reference tapered slot Vivaldi antenna is first designed for UWB operation that is, 3.1–10.6 GHz using the standard procedure. The band-notch operation at 4.8 GHz is achieved with the help of especially designed comple...

The design of a simple small-size antenna for worldwide interoperability for microwave access (WiMAX) application is presented in this paper. The antenna covers the 3-5 GHz WiMAX band. The proposed printedtype antenna is based on a 1.6 mm-thick FR4 epoxy substrate with dimensions W=25 mm and L=40.5 mm. It has a rectangular split-ring slot enclosed inside a rectangular patch. The inclusion of th...

This paper proposes a low-voltage and low-power fully integrated digitally tuned continuous-time channel selection filter for WiMAX applications. A 5-order elliptic low-pass filter is realized in a Gm-C topology. The bandwidth of the fully differential filter is reconfigurable from 2.5MHz to 20MHz (8x) for different requirements in WiMAX applications. The filter is simulated in a standard 90nm ...

In this article, an UWB (Ultra-wide Band) compact monopole antenna with triple band-notched characteristics is presented. The proposed structure designed on the FR-4 substrate εr=4.3, tan δ = 0.025. consists of half-hexagon rectangular and square resonant spirals structures for exclusion frequency bands WiMAX (3.25-3.85GHz), WLAN(5.15-5.85GHz) Fixed/Mobile Satellite Communication (7.55-7.75GHz)...
