Design Techniques of Super-Wideband Antenna–Existing and Future Prospective

Abstract

With the recent advancement and phenomenal progress in the field of wireless communication technology, there is an ever increasing demand for high data rates and improved quality of service for the end users. In recent times various designs of super wideband antennas (SWB) fulfilling diverse objectives have been proposed for modern wireless networks. Design of compact and wideband antenna for high speed, high capacity, and secure wireless communications presents a challenging task for designers of fixed and mobile wireless communication systems. In this paper, a comprehensive review concerning antenna structures and the technologies adopted for design and analysis of SWB antennas for wireless application is reported. Comparative parameters in terms of electrical dimension, bandwidth, Fractional bandwidth (FB) and Bandwidth Dimension Ratio (BDR) are presented which introduces the researchers to the technical challenges in the design of a compact wideband antenna. This paper contributes to present existing novel approaches along with its adequacy in the design techniques. This review exercise will assist the researchers with valuable support for further research and to achieve better impedance matching, wide bandwidth, high gain and good efficiency along with well directive radiation characteristics.INDEX TERMS Bandwidth dimension ratio, compact design, fractal antenna, monopole antenna, super wideband antenna.

Design of novel super wide band antenna close to the fundamental dimension limit theory

“…Although the proposed antenna in 21 claims to offer a ratio bandwidth of 111.1:1, however, this antenna does not essentially cover the entire SWB band in an uninterrupted manner, since it is designed to suppress the 4.7-6 GHz 21 . A comprehensive survey on SWB antenna-based papers is illustrated in 27 . It provides a thorough comparative analysis between the reported antennas based on various parameters.…”

Design of Quad-Port MIMO/Diversity Antenna with Triple-Band Elimination Characteristics for Super-Wideband Applications

“…In contemporary wireless communication, the demand for super-wideband (SWB) and ultra-wideband (UWB) antennas is on the rise [1,2]. The UWB antenna possesses a bandwidth ratio of 3.4:1, and its bandwidth is defined from 3.1 to 10.6 GHz (by the Federal Communications Commission) [3], while the SWB antenna offers a bandwidth ratio of more than 10:1 [4,5].…”

Design of SWB MIMO Antenna with Extremely Wideband Isolation

“…All these techniques have been employed to reduce coupling in the range 3.1 GHz-10.6 GHz. Further, mutual coupling reduced by metamaterial in [30][31][32][33][34][35][36][37][38][39] and [40][41][42][43]. Most of these antennas possess large dimensions, have low isolation enhancement and low %BW and gain.…”
