Abstract
AbstractThe design and analysis of step impedance resonator (SIR) based, compact and band-notch UWB antenna, to minimize the potential interference between wide-band (UWB) and narrow-band (WLAN), has been presented in this paper. The notched band covers the 5.15 GHz to 5.85 GHz WLAN range. The frequency band has been obtained by embedding a SIR near the radiating patch of the antenna. The empirical relationship between the SIR design and band-notch characteristics has also been included in the paper. The UWB patch antenna structure is feed by micro-strip line. The parametric-analysis by varying the parameters the SIR as well as the substrate has been performed, to observe the optimal performance the proposed antenna. The design and functional simulation of the proposed antenna structure is performed by using HFSS-v14. A close agreement between simulated and experimental results for the proposed design has been observed and presented in this paper. The design and results provide ample justification for com...
Highlights
The Ultra wideband (UWB) antenna design plays a unique role because it behaves like a band pass filter and reshapes the spectra of the pulses and avoid undesired distortions
The Ultra wideband (UWB) is a wireless communication technology, which provide a short-range communication from 4 meters to10 meters, with a low output power and high data rate in 3.1–10.6 GHz the frequency range (Federal Communications Commission, 2002)
The design of an UWB antenna with band-notch characterstics is a prime requirement to diminish the potential interference between UWB and co-existing narrowband services
Summary
Wireless connectivity has enabled a new mobile lifestyle filled with conveniences for mobile computing users. Today’s wireless LAN and WPAN technologies cannot meet the needs of tomorrow’s connectivity of such a host of emerging consumer electronic devices that require high bandwidth. Ultra-wideband (UWB) technology offers a solution for the bandwidth, high data rates across multiple devices, cost, power consumption, and physical size requirements of next-generation consumer electronic devices for digital home and the office. In this context, the UWB antenna design plays a unique role because it behaves like a band pass filter and reshapes the spectra of the pulses and avoid undesired distortions
