MICROWAVE ENGINEERING & MICROWAVE AND RADAR ENGINEERING

Microwaves are a form of electromagnetic radiation with wavelengths ranging from as long as one meter to as short as one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm).This broad definition includes both UHF and EHF (millimeter waves), and various sources use different boundaries. In all cases, microwave includes the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum, with RF engineering often restricting the range between 1 and 100 GHz. These manuals are helps the engineering students to get study himself and get aware about the technology.

ANTENNA & WAVE PROPAGATION

Antenna & Wave Propagation

Antennas play vital role in wireless communication as a terminal component of transmitter and
receiver systems. The quality of signal at receiver depends on type of transmitting and receiving
antennas, their orientation, transmitting frequency and geographical terrain. For installation &
maintenance of wireless systems, the basic knowledge of wave propagation theory is essential and the
technician is required to handle a variety of antennas. This course will help the students to select an
antenna of desired operating frequency.  

Observe the various components on the motherboard, identify it

The motherboard represents the logical foundation of the computer. In other words, everything that makes a computer a computer must be attached to the motherboard. From the CPU to storage devices, from RAM to printer ports, the motherboard provides the connections that help them work together.

The motherboard is essential to computer operation in large part because of the two major buses it contains: the system bus and the I/O bus. Together, these buses carry all the information between the different parts of the computer.

Study the Steps to assemble the computer

Identify common ports, associated cables, and their connectors.

A port:

• is a physical docking point using which an external device can be connected to the computer.
• can also be programmatic docking point through which information flows from a program to computer or over the internet.

Characteristics

A port has the following characteristics:

• External devices are connected to a computer using cables and ports.
