What Are The Different Types of Antenna Polarization?

The most common types of antenna polarization are vertical, horizontal, right hand circular, or left hand circular, and antenna polarization is a critical aspect of antenna performance. The polarization of an antenna is based on […]

Terminal Antenna

RFID — Radio-Frequency Identification — provides a unique identifier for that object and just as a bar code or magnetic strip the RFID device must be scanned to retrieve the identifying information. An RFID system […]

How Antennas Work

We can’t see them but radio and television waves are just another form of light. They have a much longer wavelength than visible light but both are electromagnetic radiation. To generate radio and TV waves […]

Types of Antennas in Telecommunication

Antennas are an essential part of radio telecommunications equipment, bridging the gap between electronic and electromagnetic signals. The shape and size of an antenna is a strong clue as to its type, as the design […]

Antenna Basics: Radiation Patterns, Permittivity, Directivity, and Gain

Antennas transfer information between locations by altering electromagnetic fields in one location and detecting changes in electromagnetic fields in another location. To understand how antennas can transfer information to increasingly remote locations, you must first […]

Antenna Basics

Antenna Fundamentals Let’s get right down to the study of antennas and Antenna Basics. Suppose one day you’re walking down the street and a kind but impatient person runs up and asks you to design an […]

An Introduction to Antenna Basics

Antennas are used to transmit and receive information through changes in the electromagnetic fields that surround them. This article is a primer on antenna theory. An Abridged History of Electromagnetism Over 2600 years ago (and […]

Antenna Theory History

What is the origin of the antenna? I’m ruling out such early devices as compasses, because while they in some sense receive a magnetic field, it is not an electromagnetic field. Ben Franklin’s kite experiment […]

Radio Frequency (RF and RFID) Tags

How many times have you walked through a store’s doors and—to your extreme embarrassment—set off the anti-theft alarm? It’s surprisingly easy to do, even when you’ve paid for your item and had it “deactivated” at […]
