Embodiment 1
[0035] See figure 1 , figure 2 with image 3 The dual-polarized diagonal beam waveguide slot array antenna includes a unit array antenna, and each unit array antenna is composed of a horizontally polarized linear array and a vertically polarized linear array.
[0036] See Figure 4 , The horizontally polarized linear array includes two parallel horizontally polarized single-ridge waveguides 1. The horizontally polarized single ridge waveguide 1 has a wide-sided V-shaped radiation slot 3, and the adjacent V-shaped radiation slots 3 are arranged at equal intervals; one end of each horizontally polarized single ridge waveguide 1 is terminated with a horizontally polarized ridge waveguide to coaxial conversion The device 5 is matched with a 50 ohm SMA load; the other end is connected through a curved ridge waveguide 7 and a horizontally polarized feeder network 11, and fed through a horizontally polarized feeder waveguide 10 to form a horizontally polarized linear array, see respect...
Embodiment 2
[0044] See Picture 10 , Picture 11 with Picture 12 , Dual-polarized oblique beam waveguide slot panel antenna is composed of six unit array antennas in parallel. The feeding end of the horizontally polarized single-ridge waveguide 1 of the six horizontally polarized linear arrays passes Picture 11 The feeder network shown is synthesized, Picture 11 The feeder network shown directly terminates a curved ridge waveguide 7 connected to each single ridge waveguide. Picture 11 The feeder network shown is composed of several horizontally polarized feeder networks 11 and unequal power dividers 14. The horizontally polarized feeder network 11 functions as an equal power divider. The entire network divides the power into 12 equal parts. The main transmission waveguide of the network is a single ridge waveguide with the same size as the horizontal polarization single ridge waveguide 1, and the single ridge waveguide is converted into a half-height waveguide by the ridge waveguide to r...
