An innovative switching multi-beam network for triangular arrays of three radiating elements is proposed. This novel network provides three orthogonal beams in a desired elevation angle and a fourth one in the broadside steering direction. The network is composed of four-port 3-dB quadrature hybrid power couplers and fixed phase shifters. In this paper, a relation between network components, radiating...
An innovative dissipative multi-beam network for triangular arrays of three radiating elements is proposed. This novel network provides three orthogonal beams in θ0 elevation angle and a fourth one in the broadside steering direction. The network is composed of 90° hybrid couplers and fixed phase shifters. In this paper, a relation between network components, radiating element distance and beam steering...
Nowadays, ground stations requirements make it more and more necessary to incorporate conformal antenna structures like dome geometries, as they have many advantages over mechanically controlled reflector antennas. Multi-beam ability and interference rejection are facilitated thanks to the electronic control system of such antennas that improves the ground stations versatility. GEODA is a smart, conformal...
