Design of multiband fractal antenna for wireless application

Abstract

This Research work focus on innovative linear and non-linear fractal newline antenna design for different wireless applications. A nonlinear ground fractal newline antenna design, named Embedded V-Integrated Rectangular Slotted Triangle newline Edged (EVI- STE) antenna for wireless communications is designed. In this newline design slots of different shapes have been loaded in patch and in ground for newline optimization and the characteristics of an antenna such as return loss, newline impedance matching, gain and radiation pattern are evaluated. The EVI- STE newline is employed with defected ground to reduce the return loss and the antenna is newline fed by microstrip line. Antennas are designed on low cost FR-4 glass epoxy newline substrate with relative permittivity of 4.4 and overall dimension 21×25mm2. newline Comparison among antennas have been made and found that the proposed newline antenna exhibit better results in terms of bandwidth, impedance matching, newline number of frequency bands, and gain. The antenna is designed and simulated newline using HFSS and obtained good output response at 3.8, 5.6,8.2 GHz which newline makes it suitable for 5G applications. newline This investigation also aims to build a brand-new Diamond Fern newline Fractal Antenna (DFFA) with a microstrip patch line to be utilized in car newline application systems. The suggested antenna is distinct from previous newline examples in that its patch is oriented in a manner that is intended to maximize newline bandwidth while simultaneously lowering return loss. A linear slots are newline inserted into the diamond patch, manufactured in this design based on an newline inexpensive FR-4 glass epoxy substrate with a relative permittivity of 4.4 and newline an overall dimension of 25 X 25 X 1.6 mm3. In addition, it assists in the newline enhancement of the multi-band features as well as the bandwidth, and its newline efficacy is tested with the assistance of design equations and HFSS simulation newline software. In addition, the technique for the parameter extraction of the newline suggested DFFA design is thoroughly explained. newline
