Effects of Reflection, Diffraction and Refraction on Radio Frequency

The atmospheric environment with which radio frequency waves may be propagated and transmitted presents itself with a variable of impediments. Thus, waves may be reflected, diffracted or refracted depending upon the nature of the barrier, whether it is a conductor, semi-conductor, or non-conductor, and the frequency of the waves.

Radio Frequency Transmission and Reception

Conventionally, radio frequency waves were used as carriers of information depending upon the couplings used to produce specified series of charges acting as codes. These carrier waves may then be intercepted by a receiver in a reader system. The antenna would again vary depending upon the volume of information it is enabled to receive or transmit.

Radio frequency identification commonly known as tags come in a variety of Company tailor-made style with comparable if not as good as features employed in the market. As a tag the transponder is invented with an integrated circuit or IC fixed to a transmitter. This combination is secured in between shield. The set may be contained to a size desired by the consumer. Sometimes it comes in as large as a credit card, and sometimes as small as a fraction of a centimeter.
It is usually the transmitter size, transmission range, and its role in the merchandize that correspondingly determines its dimension.
