Bio-inspired wideband antenna for wireless applications based on perturbation technique

Abstract

The evolution of advancement in communication technologies and ever-increasing demand by users for compact communication devices has necessitated a shift in the design approach to achieve antenna structures that are compact and robust. Owing to the diverse communication requirements, antenna systems operating across wide bands have become a necessity. An antenna that is capable of working effectively in several bands is called wideband antenna. In this work, a bio-inspired microstrip antenna (Bi-MPA) for wideband application is proposed and simulated. The radiating patch of the proposed Bi-MPA is the shape of Carica Papaya leaf. The structure was realized through the perturbation of the circular shape patch. The proposed antenna has an impedance bandwidth of 4.3 GHz (1.9 GHz–6.2 GHz) at a return loss of 10 dB while it exhibits a narrow band at 7.2 GHz (6.99–7.44 GHz) and 9.3 GHz (9.15–9.35 GHz) bands. The gain of the proposed antenna is between 2.60 dB and 10.22 dB and the radiation pattern is quasi-omnidirectional. The proposed Bi-MPA is compact and suitable for global system for mobile communication (GSM1900), Universal Mobile Telecommunication System (UMTS), Wireless Local Area Network (WLAN), Long Term Evolution (LTE2300 and LTE2600), Worldwide Interoperability for Microwave Access (WiMAX), C-band, X-band, and sub6 GHz fifth-generation (5G) band. Our contribution to the scientific community in this work is that we have proposed a single antenna structure that is suitable for communication in all the bands mentioned in order to ensure compactness in the mobile devices as compared to base station antennas.

A Comparative Study of Compact Multiband Bio-Inspired Asymmetric Microstrip Fed Antennas (BioAs-MPAs) for Wireless Applications

“…erefore, incorporating the two bands in a single antenna element is necessary to reduce the aircraft overall weight and minimize cost. e proposed patch shapes are based on (1) the Papayaleaf shape first reported in [19] where the authors used a full papaya-leaf shape as the radiating patch for a wideband application; (2) Monstera deliciosa-leaf; and (3) Vine-leaf.…”

Maple-Leaf Shaped Broadband Optical Nano-Antenna with Hybrid Plasmonic Feed for Nano-Photonic Applications

“…Nature-inspired designs have brought tremendous technological advancements for various applications in recent decades. Antenna geometries based on bio-inspired shapes have been investigated in recent literature, where a flower shape is used to obtain a large bandwidth [2] or a papaya leaf shaped antenna provides a multi-band operation [3]. In terms of antenna array, a four-leaf based antenna is also explored [4] for low frequency applications.…”
