This communication describes a wideband switched-beam antenna fed by a compact single-layer beamforming network. First, a novel hybrid coupler structure that can provide an arbitrary phase difference over a bandwidth larger than 58% is proposed with

For a conventional coupler based on coupled-line structure, it is difficult to realize tight coupling in reality due to the limitation caused by the very narrow coupling gap. To solve this problem, two configurations are proposed in this paper. First

The existing arbitrary phase difference hybrid couplers usually have limited bandwidths due to the much more complex requirements for implementing non-standard phase difference. To effectively extend the bandwidth of a two section branch line coupler
