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 […]

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 […]

Yagi Antenna / Yagi-Uda Aerial

The Yagi antenna or aerial sometimes called the Yagi-Uda antenna is widely used where gain and directivity are required from an RF antenna design. The Yagi antenna or Yagi-Uda antenna or aerial is a particularly […]

Antenna Theory – Basic Parameters

The basic communication parameters are discussed in this chapter to have a better idea about the wireless communication using antennas. The wireless communication is done in the form of waves. Hence, we need to have […]

Antenna Theory – Fundamentals

A person, who needs to convey a thought, an idea or a doubt, can do so by voice communication. The following illustration shows two individuals communicating with each other. Here, communication takes place through sound waves. However, […]

Antenna Theory: aerial basics

Antennas are a key element of any radio system. An antenna is required to radiate and receive the signals and therefore their performance is key to the operation of the overall radio system. If the […]
