A novel microstrip antenna for triple-band WLAN/WiMAX applications is presented. Based on a face-shaped slot, the antenna consists of a pair of symmetrical eye-like patches, a smilingmouth-shaped feeding line and a rectangular stub that looks like the fringe. The resonant mode at 3.5GHz is excited by the basic radiation patch with the face-shaped slot. By adding a rectangular fringe-shaped stub...

In this paper, a wide-slot triple band antenna fed by a coplanar waveguide (CPW) for WLAN/WiMAX applications is proposed. The antenna mainly comprises a ground with a wide square slot in the center, a rectangular feeding strip and two pairs of planar inverted L strips (PIL) connecting with the slotted ground. By introducing the two pairs of PIL’s, three resonant frequencies, 2.4/5.5GHz for WLAN...

In this paper, a novel microstrip-fed compact antenna with triple band-notched characteristics is presented for ultrawideband (UWB) applications. The antenna consists of a circular radiating patch, a 50 Ω microstrip feed line, a partially slotted ground plane, and a pair of modified capacitance loaded loop (MCLL) resonators. The novel resonators are symmetrically located in the vicinity of the ...

A novel ultra-wideband (UWB) monopole antenna with triple band-notched functions is presented. A pair of folded multiplemode resonators (MMR) symmetrically coupled to the feed line are utilized to generate triple notched bands for WiMAX, WLAN and downlinks of X-band satellite communication, respectively. The centre frequencies and band gaps between them can be tuned by varying the length and wi...

For a planning of indoor Wireless LAN systems working in the ISM band, the signal propagation prediction is needed. In this article, the measurement campaign based on two types of measurements at 2.45 GHz is introduced. The first type of the measurement was a classical narrowband signal level measurement within indoor scenario without presence of people. The aim of this measurement was to find ...

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...
