Design and Assessment of Bio-Inspired Antennas for Mobile Communication Systems

Abstract

RF front-end system in the mobile communication system consists of an antenna, filter, and amplifier section. Now a day, there is a need to reduce the size of this RF front-end system. Here the challenge is the reduction in the size of the RF front end without degrading the performance. One way to reduce the size is by reducing the size or area of the antenna. This work proposes and simulates three Bio-inspired microstrip (BIMS) antenna designs. They are flower, Butterfly, and leaf shapes presented based on the perturbation method, Gielis super formula, and modified polar transformation models, respectively. These BIMS antennas were printed on fiberglass laminate (FR4) as substrate with a dielectric constant of εr = 4.4 and a loss tangent of 0.02. The simulation results cover parameters of the antenna, such as reflection coefficients (S11), surface current density (Jsurf), and radiation patterns. They offer a maximum gain of 14 dBi, 8 dBi, and 4dBi, respectively, and their results are compared with other works. These antennas are less in size, so they occupy less area compared to conventional rectangular or circular patch antenna, which radiates in L and S bands at different frequency ranges.

Investigation of Split Ring Resonator Based Rectangular Micro-Strip Patch Antenna for Radar Communication

“…Radar communication is getting emphasized constantly especially with the inevitable role in the areas like air traffic control, speed detection, military applications principally in electronic warfare [1]. Micro strip patch antennas and Printed antennas are common candidates for radar communication and for mobile and satellite equipment [2]. Most commonly used antenna type in wireless communication is the low profile micro strip patch antennas due to its idiosyncratic behavior.…”

Design Implementation of Trapezoidal Notch Band Monopole Antenna for LTE, ISM, Wi-MAX and WLAN Communication Applications

“…Ramya [12] proposed a triple band notch type monopole antenna with a complimentary split ring resonator structure for improving directivity in the operating bands. Ibrahim [13] designed a fractal antenna for various wireless communication systems applications. Hua and Yan [14] designed a notch band antennas with reconfigurability and a C-slot.…”

A Compact CPW-Fed Textile-Substrate-Based Half-Circula Spike Monopole Antenna

“…An antenna optimized for use with wearable communication systems is a coplanar waveguide-fed half-circular spike monopole antenna mounted on a textile substrate [7]. Its portability, light weight and ease of incorporation into clothes make it well suited for use in healthcare monitoring, sports tracking, military equipment, smart clothing and other related fields [8]. These antennas enhance the form and function of wearable electronics by being low-profile and easy to wear, as well as providing better signal quality than previous designs [9].…”
