CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
While working in BHEL Electronics organization, I got the idea of executing a project
on three concentric half ring microstrip patch antenna. The communication devices are
considered as one of the major and the most significant requirements for every individual for
communicating with other individuals. Electromagnetic waves are transmitted into the space
after converting electric power to radio waves. Various types of antennas are present,
however, I have selected microstrip antenna in this particular project. Various advantages like
easy plantation and easy designing were the major reasons that I selected microstrip antenna.
I designed and analyzed a three concentric half ring microstrip antenna. The proposed
antenna was being fed with a coaxial feed which is a contacting feed and was easy to
fabricate. Therefore, in this project, I provided a design for the microstrip antenna for making
it more improvised and effective.

CE 2.2.2 Objectives developed for the project
I had to ensure that my proposed design is perfect and is quite efficient and effective.
I designed a 3 concentric half ring microstrip antenna so that the half rings are arranged in a
cascaded fashion to increase the gain parameter. Hence, to complete the project with utmost
efficiency as well as priority, some of the important objectives were developed by me.
 To design as well as analyze a three concentric half ring microstrip antenna.
 To increase the gain parameter and reduce return loss of the microstrip antenna for
maintaining efficiency.
 To make the antenna applicable for military devices, wireless fidelity and also
applications of WLAN.
 To complete the entire simulation of the project with the help of High Frequency
Structural Simulator or HFSS electromagnetic simulation software tool.
 To test the simulation results with the help of a network analyzer.
 To set up the entire experiment with proper tools and techniques.
 To match and contrast the experimental result with my desired results.
CE 2.2.3 My area of work
Being a successful electronics engineer, it was quite easier for me to provide the
design of the three concentric half ring microstrip patch antenna and hence I was selected as
the chief electronics engineer. I had been experimenting with various types of antenna for
several days and thus, when I got the chance of executing such a project, I selected HFSS
electromagnetic simulation software tool as the project integration software. My project
supervisor has confidence on me and gave the core responsibility of designing the project.

CE 2.2.5 My responsibilities throughout the project
During the accomplishment of the project, I comprised of various responsibilities. My
most noteworthy duty was to propose a proper design for the three concentric half ring
microstrip patch antenna. My other responsibility was to study how the performance of the
antenna depends on various parameters of designed microstrip patch antenna. I even solved
the issue for antenna systems related to electromagnetic interference from the existing
frequency bands as there are several wireless narrowband applications, which are allocated
for the different frequency bands in UWB band. I focused on the aspect that my designed
antenna has high gain and minimum return loss. Being an expert in HFSS electromagnetic
simulation software tool, I completed the simulation and ensured that there exists no kind of
complexity in the project. I also tested the results on the network analyzer to compare with
my desired results.
