Sometimes called an aerial, an antenna is an electronic device used to transmit data. It accomplishes this by converting electricity into electromagnetic, either micro or radio, waves. Antennas are used in many devices such as wireless routers, televisions, Bluetooth enabled devices, car stereos, ...
Usage:communication antennas, television antenna, radar antenna Working frequency band:short wave antenna, ultra-short wave antenna, microwave antenna Direction:omnidirectional antenna, directional antenna, smart antenna Omnidirectional Antenna The goal of an omnidirectional antenna is to radiate energy equally...
An antenna is a device for radiating or receiving radio signals. An antenna that transmits signals does so by converting electrical current into electromagnetic radio waves. An antenna that receives signals does so by converting electromagnetic waves back into electric current. An antenna map is an ...
An antenna tuning unit, ATU or antenna tuner is an item consisting of inductors and capacitors that is used to tune an antenna so that it matches the feeder and reduces the SWR.
An antenna ball is a decorative item that is attached to the top of a radio antenna, often seen on cars. In most cases, an...

An antenna array is a beam switching technology that comprises of a number of tiny antennas with several antenna elements that can be enabled or disabled separately. Each small antenna can be used as an omnidirectional or directional antenna, and how they are assembled affects their strength, pola...
“directivity”. An isotropic antenna is said to have “no gain”. “No gain” can be expressed in linear terms like x1 (times 1). That simply means that all directions have the same energy radiation, and are all equal to the average energy radiation. Antenna engineers like logarithmic ...
