Abstract
An electronically reconfigurable beam switching array antenna applicable to MIMO technology in the 2.4 GHz band is proposed in this work. The array antenna contains a Rotman lens and four element antennas. The Rotman lens, which is a true time delay device, allows simultaneous operation of multiple beams. The simple beam switching mechanism implemented with the Rotman lens suits well to the MIMO transceiver need. Coupling among antenna ports, beam ports, and dummy ports in the Rotman lens are examined via simulation and prototype measurement. Beam switching performance of the proposed system is verified.
