Information about Antennas

Antennas are structures used to collect or radiate electromagnetic waves. Antennas can be considered specialized transducers that convert RF fields into AC line signals or vice versa. The two main types of antennas are the receiving antenna, which intercepts RF energy and delivers AC to electronic equipment, and the transmitting antenna, which is fed with AC from electronic equipment and generates an RF field.

Products & Services Related to Antennas

Access Points

Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure.

Diplexers and Duplexers, RF

RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.

Horn Antennas

Horn antennas are used for the transmission and reception of microwave signals. They are usually fed by waveguides.

Navigational Instruments and Avionics

Navigational instruments and avionics include GPS devices, compasses, chronometers, radar units and other instruments for orientation, relative position and absolute position (longitude / latitude).

Radar Systems and Products

Radar systems and products have synchronized transmitters and receivers that send radio waves and detect their reflections from objects, surfaces or sub-surface structures.

RF Repeaters

RF repeaters have independent paths for reception and transmission, through which they collect and send signals to antennas and other stations.

RF Waveguide Components

RF waveguide components are circular, elliptical or rectangular metal tubes or pipes through which electromagnetic waves are propagated in microwave and RF communications. The wave passing through the medium is forced to follow the path determined by the physical structure of the guide.

Towers, Poles and Support Structures

Towers, poles and support structures elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines.

Wireless Modems

Wireless modems transmit modulated data using electromagnetic waves.

Wireless Systems

Wireless systems consist of combined RF components such as transmitters, receivers, transceivers, filters, down / up converters, antennas and antenna positioners.
