摘要： Antennas with increased bandwidth are provided. The bandwidth of an antenna can be increased by feeding it at a single point through N sides with a 1:N power divider, where N is an integer greater than 1. This bandwidth enhancement approach can be applied to different types of antennas, and with this design approach the bandwidth of an antenna can be increased without increasing its footprint.

摘要： Ultrawideband (UWB) beamforming networks are provided. A UWB beamforming network can have azimuth angle scanning and elevation angle scanning. A modified version of the Blass matrix topology can be used to achieve two-dimensional (2D) scanning behavior. The beamforming network can simultaneously excite a plurality of beams, and each of these beams can be at any chosen frequency inside the bandwidth that the beamformer covers. Each beam can be designed to point at any arbitrary direction, which can be defined by the desired elevation angle and azimuth angle, in the 2D plane.
