Ultra-wide band (UWB) communication technology has received much publicity over the years as
the most efficient solution for short distance wireless data communication. This is due to the large
unlicensed bandwidth provided by the Federal Communications Commission (FCC) for UWB
communications. Also, UWB technology is well suited to high-level data communications such as
multimedia video streaming.
Moreover, as the world welcomes the beginning of the Internet of Things (IoT) era, the UWB
Communication recovers some attention in home-based, home-based systems network systems
and internal communication of health care systems. In these application areas, device
manufacturers are interested in making their devices more portable as well as equipped with a
high-level data connection. UWB technology meets these requirements.
This thesis introduces the design and analysis of a new two-hole band Ultra-wide multiple-inputmultiple-output (UWB-MIMO) antenna for multi-band wireless application.
The proposed MIMO antenna achieves maximum variation on a single monopole note and so on
thus suitable for high-speed wireless applications. To build a MIMO antenna, first, a UWB
monopole antenna is carefully designed by cutting the beveling slot on the sides of a rectangular
monopole antenna. This process improves the impedance bandwidth of an antenna and also helps
to achieve multiband resonance features. The antenna reaches a 5.5 GHz bandwidth with 5 GHz,
6 GHz, 7 GHz and 9 GHz audio modes respectively. This makes the stick suitable for wireless
multi-band communication.
These two the port MIMO antenna is then designed by removing the monopole antenna from the
planar FR4 dielectric substrate size 34 *72 mm2
. Each MIMO feature is a feed separated by a feed
line of 50Ω microstrip.
Also, this thesis presents a detailed analysis of effects of bevel spaces, antenna size, and spacing
distance between features of the MIMO antenna in the performance of the proposed UWB
monopole antenna and the MIMO antenna as well. The results are simulated with the help of a
three-dimensional (3D) high frequency structure simulator (HFSS) simulation software.
Imitation effects indicate that the antenna is suitable for the multiband wireless system UWBMIMO. |
