DESIGN OF BIO INSPIRED TULIP FLOWER SHAPED 2X2 MIMO ANTENNA FOR 5G APPLICATIONS

Abstract

[06] In this project, a Bio Inspired Tulip shaped 2x2 (Multiple input Multiple output) MIMO antenna for 5G applications is presented. The proposed antenna is designed to resonate at 4.5 GHz to 13 GHz frequency. The designed antenna has a wide bandwidth. The micro-strip patch antenna uses FR-4 as substrate which has the dielectric constant εr = 4.4 and the tangent loss of 0.02. It consists of two tulip shaped radiating patches present on the top of the substrate. Micro-strip feed line mechanism is used as a feed technique. The radiation characteristics such as return loss, VSWR, radiation pattern and gain are simulated and presented using Ansoft HFSS software. The prototype model of the proposed antenna will be tested using Network Analyzer, results will be compared between measured and simulated results. Accompanied Drawing [FIG. 1]

Description:[01] FIELD OF THE INVENTION
The present invention relates to the design of bio inspired tulip flower shaped 2x2 MIMO antenna for 5G applications.
[02] BACKGROUND OF THE INVENTION
Today antenna plays a vital role in communication system. Antenna is used in a wide range of applications including radio and television broadcasting, wireless communication system, radar systems satellite communications, medical, and defense etc. An antenna is an electrical device that is used to transmit or receive electromagnetic waves. It converts electrical signals into electromagnetic waves and vice versa. Advancement in technology and evolution in communication has led to the need for having a compact sized antenna which can be easily integrated in any substance and has a low signal to noise ratio, low interference etc. This leads to the invention of micro-strip patch antenna. This micro-strip patch antenna is preferred over other antennas for wireless applications due to its low weight, low cost, low fabrication cost etc.
