ANTENNA ARCHITECTURE FOR MAINTAINING BEAM SHAPE IN A RECONFIGURABLE ANTENNA |
摘要 |
A node in a wireless communication system comprising an antenna array with at least a first antenna function and a second antenna function. The node further comprises a first radio chain and a second radio chain, where each antenna function is connected to a base band via a corresponding radio chain. Each radio chain comprises an oscillator, a splitter and a multiplexer, each oscillator being arranged to feed a signal with a unique frequency band to the splitter in the same radio chain. The splitter is arranged to divide the signal into at least two signal parts and feed each part to the multiplexer of each radio chain such that each multiplexer in the node receives signal parts from each splitter in the node. The splitter is arranged to weight the division of the signal into the signal parts in dependence of the frequency bands fed by each oscillator. |
