What Is RF and Why Do We Use It?

Learn about electromagnetic radiation and why it is so useful for wireless communication. When we think of electricity, we naturally think of wires. From high-voltage transmission lines to tiny traces on a printed circuit board, […]

What are Distributed Antenna Systems (DAS)?

A Distributed antenna system (DAS) is a network of antennas, connected to a common source, distributed throughout a building or an area to improve network performance. The spacing between antennas is such that each antenna gives full […]

Distributed Antenna System (DAS)

A distributed antenna system (DAS) is a way to deal with isolated spots of poor coverage inside a large building by installing a network of relatively small antennas throughout the building to serve as repeaters. The antennas are […]

Different Types of Antennas & Characteristics of Antenna

In this tutorial, we will learn about Antennas, what are the different types of antennas, different properties of antennas and many other important aspects of antennas. If you are interested in Wireless Communication Engineering, there will be […]

All About Antennas

The subject of antennas is often relegated to a mere footnote in many enterprise wireless networking discussions. Yet it is the antenna – the conductor that converts electrical signals to radio waves for transmission and back again […]

Distributed Antenna System (DAS)

A distributed antenna system (DAS) is a network of spatially or geographically separated antenna nodes that are connected to a common source through a transport or communication medium in order to provide wireless communication service in a […]

SCADA: Alive and Well in the Age of IoT

When most people think of the Internet of Things (IoT), home automation is what comes to mind. But in terms of complexity, home automation is a simple network compared with applications in “smart” cities, huge […]

The Dipole Antenna

In this section, the dipole antenna with a very thin radius is considered. The dipole antenna is similar to the short dipole except it is not required to be small compared to the wavelength (at the frequency the antenna […]

Dipole Antenna: Dipole Aerial

The dipole antenna or dipole aerial is one of the most important forms of RF antenna. The dipole can be used on its own, or it can form part of a more complicated antenna array. […]

What is a Yagi Antenna?

A Yagi antenna or a Yagi-Uda antenna, is a directional antenna that radiates signals in one main direction. It consists of a long transmission line with a single driven element consisting of two rods connected […]
