RF Antennas
Antennas are major components in communication systems.
Transmitting antennas efficiently radiate electromagnetic fields and match RF systems to space. Antennas may transmit or receive electromagnetic fields. Transmitting Antennas convert electric current to electromagnetic fields. Receiving antennas convert electromagnetic fields to electric current. In transmitting antennas, an alternating current is created in the elements by applying a voltage at the antenna feed network, causing the antenna to radiate an electromagnetic energy. In receiving mode, an electromagnetic field from an outer source induces an alternating current in the receiving antenna and generates a voltage at the antenna’s feed network. Antennas are used in outdoor and indoor communication systems. Antennas can be used in under water communication systems. Antennas may be implanted inside human body and operate as wearable sensors. Receiving antennas such as parabolic and horn antennas incorporate shaped reflective surfaces to receive the electromagnetic fields and focus the fields to the conductive receiving elements.
An RF antenna is used to convert electric energy into radio waves which enables communication / instruction between two points. These are usually a radio transmitter and receiver, no radio device will work without one. Depending on the applications, antennas can sometimes be as simple as a piece of wire. They work when radio waves reach an antenna and cause the electrons inside it to vibrate. This creates an electric current that duplicates they original signal.
