The application of a multibeam antenna for 4G

There are various antenna schemes which can be used to increase the throughput of the 4^th mobile generation (4G) networks such as antenna diversity, beamforming, spatial multiplexing and MIMO (Multiple Input Multiple Output) [1]. With the above antenna schemes OFDMA (Orthogonal Frequency Division Multiple Access) is a suitable selection for 4G. This paper proposes a multibeam antenna combining OFDMA for the next generation mobile communications. Analysis and simulation show that this kind of antenna is comparable to MIMO scheme and can be applied to 4G.
