Microstrip antennas come in various types based on their feeding mechanism, patch shape, operating frequency, and bandwidth. The main types include microstrip patch antennas, microstrip dipole antennas, printed slot antennas, and microstrip traveling wave antennas. Printed slot antennas comprise a slot in the ground plane of a grounded substrate and can take any shape. They are typically bidirectional radiators but can be made unidirectional using a reflected plate. Microstrip dipole antennas simply consist of two lengths of metal arranged end to end with feed in the middle. Microstrip traveling wave antennas support transverse wave propagation along periodic microstrip lines or long segments.
A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz.
Microstrip antenna (also known as a printed antenna) usually means an antenna fabricated using microstrip techniques on a printed circuit board (PCB). They are mostly used at microwave frequencies.

In radio and electronics, an antenna is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.

A rhombic antenna is a broadband directional wire antenna co-invented by Edmond Bruce and Harald Friis, in 1931, mostly commonly used in the high frequency (HF) or shortwave band.
In radio and electronics, an antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa.[1] It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antenna elements are connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship. The radio waves radiated by each individual antenna combine and superpose, adding together (interfering constructively) to enhance the power radiated in desired directions, and cancelling (interfering destructively) to reduce the power radiated in other directions. Similarly, when used for receiving, the separate radio frequency currents from the individual antennas combine in the receiver with the correct phase relationship to enhance signals received from the desired directions and cancel signals from undesired directions.

It was our first real life based designing experience on this platform. From the mentioned designed we tried to develop a prototype of Dipole antenna of 600 Mhz for practical uses. For the further development we’ve a got plan to use a simulation software like CST microwave studio or ADS to simulate our developed design in the long term . We had to work very hard to complete this design in time! But in the end, the challenge and learning experience were well worth it.
An Antenna is a transducer, which converts electrical power into electromagnetic waves and vice versa.
An Antenna can be used either as a transmitting antenna or a receiving antenna.
A transmitting antenna is one, which converts electrical signals into electromagnetic waves and radiates them.
A receiving antenna is one, which converts electromagnetic waves from the received beam into electrical signals.
In two-way communication, the same antenna can be used for both transmission and reception.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

2. Types of microstrip antennas are
based on :-
Feeding mechanism (Inset feed, CPW feed,
coupling feed etc.)
Shape of patch (square, circular, hexagonal,
fractal etc.)
Operating frequency
Band(s) of operation i.e. wideband, Multiband,
single band, dual, tri band and so on.
4. Printed slot antenna :-
Printed slot antennas comprises of a slot in the
ground plane of grounded substrate. Virtually the
slot can have any shape. Theoretically most of the
patch shapes can be realised in the form of
printed slot.
Like MSA the slot antennas can be fed either by
MS line or coplaner waveguide.
Generally bidirectional radiators, unidirectional
radiation is obtained by using reflected plate on
one side of the slot.
6. Printed slot antenna
A. Printed slot antenna fed by microstrip line
1.Printed narrow slot antenna
2.Printed wide slot antenna
3.Printed wide slot antenna generating cp
wave
B. Slot antenna fed by cpw
7. Printed Dipole Antenna
• The dipole antenna is simply two
wires pointed in opposite directions
arranged either horizontally or
vertically, with one end of each wire
connected to the radio and the other
end hanging free in space.
8. The transmission line is often known as a feed
element. When the waves reach the antenna, they
oscillate along the length of the antenna and back.
Each oscillation pushes electromagnetic energy
from the antenna, emitting the energy through free
space as radio waves.
9. Properties of dipole Antenna
A Dipole antenna’s size and shape depend on the intended
frequency or wavelength of the radio waves being sent or
received. The design of a transmitting antenna is usually not
different from that of a receiving antenna. Some devices use the
same antenna for both purposes.
Size : The electrical size of an antenna depends on the
wavelength of the radio waves being sent or received. An
antenna radiates energy most efficiently when its length is a
particular fraction of the wavelength.
Shape : Antennas come in a wide variety of shapes. One of the
simplest types of antennas is called a dipole. The two lengths
of metal are usually arranged end to end, with the cable from
the transmitter or receiver feeding each length of the dipole in
the middle.
10. The Dipole Antenna Parameter
There are several critical parameters that affect an
Dipole antenna's performance and can be adjusted
during the design process.
Resonant frequency
Impedance
Gain
Polarisation
Efficiency
Bandwidth
11. Common application of Dipole
Antenna
Set top TV antenna - The most common dipole
antenna is the "rabbit ears" type used with televisions.
These are adjustable in length and angle.
Folded dipoles - Another common place one can see
dipoles are as antennas for the FM band - these are
folded dipoles.
13. What is micro-strip travelling wave
antennas?
• concatenated sections of periodic micro-
strip lines or long segments of sufficient
bandwidth.
• support the propagation of transversely
electric (TE) waves.

17. WHAT IS MICRO-STRIP
PATCH ANTENNA ?
A Micro-strip patch Antenna (MSPA) in its simplest form
consists of a radiating patch on one side of a dielectric
substrate and a ground plane on the other side.
MSPAs are also known as “patch antennas” or “printed
antennas” or “planar antennas”.
