From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For other uses‚ see Radar (disambiguation). A long-range radar antenna‚ known as ALTAIR‚ used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on Kwajalein Atoll. Israeli military radar is typical of the type of radar used for air traffic control. The antenna rotates at a steady rate‚ sweeping the local airspace with a narrow vertical fan-shaped beam‚ to detect aircraft at all altitudes

the use of antenna arrays in interference cancellation and for receive diversity. This final chapter takes a broad view of the use of antenna arrays in wireless communications. In particular‚ we will investigate the capacity of systems using multiple transmit and/or multiple receive antennas. This provides a fundamental limit on the data throughput in multipleinput multiple-output (MIMO) systems. We will also develop the use of transmit diversity‚ i.e.‚ the use of multiple transmit antennas to achieve

Lens Antenna an antenna whose directivity pattern is a result of the difference between the phase velocity of propagation of an electromagnetic wave in air and that in the lens material. Lens antennas are used in radar and metering equipment that operates in the centimeter wavelength range. A lens antenna consists of a lens proper and of a feed. The shape of the lens depends on the refractive index n (the ratio of the phase velocity of propagation of a radio wave in a vacuum to that in the lens)

Multipath is the propagation phenomenon where transmitted information collides with ceilings‚ walls and other objects‚ which reaches the receiving antenna multiple times via different angles and at slightly different times causing a reduction in data speed and an increase in the

For the traditional 2G/3G distributed antenna systems with single-path single-polarized antenna‚ it is required to upgrade to multiple antennas. Abstract—With the development of Internet and 3G communication systems‚ the requirement of data transmission is increasing. Multi-Input-Multi-Output (MIMO) as one of the important techniques

reaching the receiving antenna multiple times via different angles and at slightly different times. In radio‚ multiple-input and multiple-output‚ or MIMO (commonly pronounced my-moh or me-moh)‚ is the use of multiple antennas at both the transmitter and receiver to improve communication performance. It is one of several forms of smart antenna technology. Note that the terms input and output refer to the radio channel carrying the signal‚ not to the devices having antennas. MIMO technology has attracted

the transmissions are focused with a desired area. When the area is focused‚ then the emissions don‟t go outside that designated area and thus minimizing the interference to the other systems. This leads more efficient spectrum usage. Satellite‟s antenna patterns play an important role and must be designed to best cover the designated geographical area (which is generally irregular in shape). Satellites should be designed by keeping in mind its usability for short and long term effects throughout
