A Novel Design of Broadband Antennas with a Defected Radiating Patch Structure for Wireless Communication Systems
Abstract
Generally, conventional wireless communication systems transfer data
between two points through a channel, consisting of broadband with a multi-frequency band. Broadband or multiband is very important in wireless
telecommunication devices. It is quickly advancing as high-speed and high-level
data rate wireless modern communication technology. In wireless modern
communication the antenna plays a very crucial role. Broadband with a multi-frequency band purpose has been the incitement of this research. However, there
are a lot of challenges in designing and accomplishing a broadband with a multi-frequency band antenna than with a tight impedance bandwidth single antenna.
Appropriate broadband with multi-frequency band antenna should be officially
recognized in which working over an especially in broadband by as exactly the
same determined by (WLAN (5.15–5.35 GHz and 5.725–5.825 GHz) Federal
Communications Commission. At the same design, good enough radiation
properties over the perfect frequency range are also compulsory. This dissertation focuses on broadband with multi-resonant frequency
microstrip patch antenna style and analysis. Studies are undertaken covering the
areas of broad with multi-band fundamentals and microstrip patch antenna theory.
In recently years, the slot width and length in the patch antenna established
itself as an effective a flexible, small, easy to install or etch on the solid surface,
and easy to fine-tune for broadband with multi-frequency-band applications. The
essential and main aim of this thesis is to suggest an effective antenna which,
practical new design procedure to design an open-slot antenna with the foam gap
and provide physical vision into the design using full-wave analysis methods
through two software packages.
This investigation systematically focuses on developing a new schema to
design broadband and multiband with an open-slot antenna and a foam gap. The
simulated software packages are used to confirm the new technology by comparing
the results and clearly show. In this design, the effect of reactive loading on the line
fed, three layers, and open slot loaded microstrip patch antenna with the gap is
investigated by the (Method of Moments) (MOM). Itemized analyses of reactive
loading appropriate to slot location and variation of slot width and length are
presented.
In this work, the design of the wideband patch antennas is considered uses
the open slot technology. The radiated antenna layer, return loss simulated, gain,
bandwidth, radiation pattern, and directivity have been investigated. The
argumentations, investigations, and results of this thesis are helpful in designing
and improving the performance of conventional characteristics patch antennas as
per the need of the community and without harm to the environment and
interference of signals.
