Abstract
A low-loss feeding network comprises a vertical switching structure, a substrate integrated waveguide (SIW), a 2-way power divider, coupling slots, matching metal vias and parallel-plane waveguides, wherein the energy provided by a standard waveguide is coupled to the SIW through the vertical switching structure, and the energy outputted by the SIW is evenly split into 2parts by the 2-way power divider; the energy of each way outputted by the 2-way power divider is coupled to parallel-plane waveguides through the coupling slots and the matching metal vias, and the electric field at the junction of two adjacent parallel-plane waveguides is zero, so that an ideal virtual electric wall is formed, thus the structure of the feeding network is simplified, and the metal loss at the junction is reduced; finally, the energy provided by the low-loss feeding network is radiated in phase through the symmetrical slot antenna array.
