About Microwave Engineering Notes

Microwave engineering is referred to as the study and design of microwave circuits, components and systems. In analysis, design and measurement techniques in this field, the applied principles are considered to be fundamental principles. Microwave engineering is distinguished from electrical engineering with the involvement of short wavelengths. This distinction happens because of different interactions that occur at microwave frequencies with circuits, transmissions and propagation characteristics.

Some devices and theories that are associated with the theory of microwave engineering are radar, antennas, transmission lines, space-based systems, microwave radiation hazards and measurements. During World War II, microwave engineering was used in developed radars which helped in locating enemy ships and planes. The radars were locating ships with the help of a focused beam of EM radiation.

Microwave engineering importance has increased over the years since World War II, which is why strengthening knowledge on this subject is essential. For understanding the concepts and operating theories of microwave engineering, students should download microwave engineering lecture notes so to get a clear overview of the subject. The notes explain every area of microwave engineering in a detailed manner.

A student with good knowledge on microwave engineering is capable of scoring good mark in the exams, and he/she can have a successful career in the future if he/she chooses to pursue his/her career in this field.

Frequently Asked Questions on Microwave Engineering Notes

Question 1.
What is a microwave in microwave engineering?

Answer:
Microwave is considered as a term that is generally used to identify electromagnetic waves that are above 103megahertz ( 1 Gigahertz) and can go up to 300 Gigahertz due to the presence of short physical wavelengths in these frequencies. Short wavelengths are known for offering a different type of advantages in many applications, for example, small antennas and low-power transmitters are capable of providing sufficient directivity. This type of characteristics makes microwaves best for use in military and civilian radars.

Question 2.
What are the applications of microwave engineering?

Answer:
The applications of microwave engineering are:

  • Antenna gain is considered proportional to the electrical size of the antenna. When the frequency is high, the antenna gain is more on given physical antenna size. This has important effects on implementing miniaturised microwave systems.
  • Higher frequencies can cause more bandwidth. Bandwidths are considered important because frequency bands available in the electromagnetic spectrum are depleted rapidly.
  • Microwave signals that used to travel by the line of sight didn’t bend from the effect of the ionosphere like the low-frequency signals, which is why terrestrial communication links of high capacities are possible.

Question 3.
What is a microwave system?

Answer:
A microwave system is a type of system which used to have a transmitter subsystem which includes a microwave oscillator, waveguides, a transmitting antenna and a receiver subsystem which includes a receiving antenna, transmission line or waveguide, a receiver and a microwave amplifier.

Question 4.
What is a microwave junction?

Answer:
A microwave junction is a point where two or more microwave devices are interconnected to each other. Some commonly used microwave junctions are waveguide tees such as E-plane tee, H-plane tee, magic tee, hybrid ring, circulator and a directional coupler. Microwave junction is also known as voltage or series junction that is present between two microwave devices.
