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...

Using composite right-left handed (CRLH) transmission line concept, a novel miniaturized dual notch band filter (DNBF) is proposed. The suggested DNBF consists of an interdigital transmission line (ITL), split ring resonators (SRRs) and complementary split ring resonators (CSRRs). Since the resonance frequency of the SRRs and CSRRs are quite independent of each other, the dual notch bands of th...

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...
