A novel tapered slot antenna (TSA) with 3.5/5.5 GHz dual band-notched characteristics for ultra-wideband (UWB) radios is proposed in this paper. To realize dual band-notched characteristics at the TSA, we employ (a) a pair of nested C-shaped stubs beside the feed line and (b) a broadband microstrip-to-slot-line transition with an Archimedean spiral-shaped slot. The proposed antenna has been suc...

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 prototype for a dual-band metamaterial-inspired antenna is presented. The antenna consists of a dual-band dipole placed between two meta-surfaces, which are tuned to operate at both dipole bands. In this way, the dipole radiates at a different half-space at each frequency band. Antenna gains as high as 6.1dB and 7.6dB have been measured at the lowand high-frequency bands, respectively, while ...

This paper proposes a monopole antenna with photonic crystal structure as substrate for ultrawide band application with dual band notched characteristics.Improvements in all the main parameters of the antenna were obtained when using a PC.The measured results reveal that the presented dual band-notch monopole antenna offers a very wide bandwidth with two notched bands, covering 3.5/5.5-GHz WiMA...

This paper presents a dual-band dual-polarized antenna array design for WLAN applications. Four double-dipole elements are orthogonally interleaved to facilitate operation in both the standard WLAN frequency bands (IEEE 802.11b and IEEE 802.11a) simultaneously. The two linear polarizations have separate ports. The presented design is characterized by dual-band operation, reasonably good front-t...

The design of a compact dual-band dual-port antenna system is presented. It operates in two frequency bands, 790862 MHz and 2500-2690 MHz, thereby making it suitable for Long Term Evolution (LTE) handheld devices. The proposed system is composed of two orthogonal inverted-F antennas (IFA) to perform diversity in mobile terminals. A good agreement is observed between simulated and experimental r...
