MIMO ARRAY ANTENNA FOR ADAPTIVE ISOLATION

摘要

An MIMO(Multiple-Input Multiple-Output) array antenna is provided to perform a proper isolation in a variable frequency environment by adaptively changing the electrical length of the isolation element. A first radiator(102) and a second radiator(104) are separated from a substrate and are arranged in parallel to the substrate. First and second short pins electrically connect a first radiator and a second radiator. First and second feed pins transmit the RF(Radio Frequency) signal to the first and second radiators. First and second isolation elements(106,108) are extended from the substrate. The electrical length of the first and second isolation elements are varied. The first and second isolation elements include the plurality of isolation elements. The plurality of isolation elements are connected by first or second switch elements.
