It also helps readers to develop the skills and knowledge to design, analyze, or evaluate wireless systems for various applications.


Microwave and RF fundamentals




Before diving into the details of microwave and RF design of wireless systems, it is essential to understand some basic concepts and definitions. In this section, we will introduce what are microwaves and radio frequencies, how are they used in wireless communications and data transmission, and what are the main challenges and trade-offs in microwave and RF design.


What are microwaves and radio frequencies?




Microwaves and radio frequencies are electromagnetic waves that have frequencies ranging from 300 MHz to 300 GHz. They are part of the electromagnetic spectrum that includes other types of waves such as visible light, infrared, ultraviolet, X-rays, gamma rays, etc. The electromagnetic spectrum is divided into different bands based on the frequency or wavelength of the waves. The following table shows some common bands used in wireless communications and data transmission.


Band Frequency range Wavelength range Applications --- --- --- --- VHF (Very High Frequency) 30 MHz - 300 MHz 10 m - 1 m FM radio, TV broadcasting, marine and air traffic control UHF (Ultra High Frequency) 300 MHz - 3 GHz 1 m - 10 cm Cellular phones, GPS, Wi-Fi, Bluetooth, RFID SHF (Super High Frequency) 3 GHz - 30 GHz 10 cm - 1 cm Satellite communications, radar, microwave ovens EHF (Extremely High Frequency) 30 GHz - 300 GHz 1 cm - 1 mm Millimeter wave communications, imaging The frequency or wavelength of an electromagnetic wave determines its properties and behavior. For example, higher frequency waves have shorter wavelengths and can carry more information or data per unit time. However, they also have higher attenuation or loss due to absorption or scattering by the atmosphere or other objects. Lower frequency waves have longer wavelengths and can propagate farther or penetrate deeper into materials. However, they also have lower bandwidth or capacity to transmit information or data per unit time.


How are they used in wireless communications and data transmission?




Microwaves and radio frequencies are used in wireless communications and data transmission because they can travel through space without requiring physical wires or cables. They can also be modulated or manipulated to carry information or data in various forms such as analog signals (e.g., voice or music) or digital signals (e.g., binary bits or symbols). The basic process of wireless communication or data transmission using microwaves or radio frequencies involves three main steps:


Transmitting: The transmitter converts the information or data into an electromagnetic wave with a certain frequency (called the carrier frequency) and amplitude (called the signal power). The transmitter may also modify the wave by changing its frequency (called frequency modulation), amplitude (called amplitude modulation), phase (called phase modulation), or a combination of these (called quadrature amplitude modulation) according to the information or data to be transmitted. This process is called modulation. The transmitter then sends the modulated wave through an antenna that radiates it into 71b2f0854b
