| Zusammenfassung: | The invention provides a Ka-band wide-angle scanning circularly-polarized microstrip antenna array and relates to the technical field of a satellite communication antenna. The Ka-band wide-angle scanning circularly-polarized microstrip antenna array is formed by M*N antenna units, M and N being an integer, M>=1, N>=2. Each antenna unit comprises an antenna portion and a base portion. The antenna portion is mounted on the base portion; and the antenna portion comprises a first antenna substrate and a second antenna substrate, wherein the first antenna substrate and the second antenna substrate are mounted on an antenna floor, and the first antenna substrate and the second antenna substrate intersect. The antenna floor is provided with a floor grounding wire. The antenna floor is also provided with four metal parasitic rods, which locate at the two ends of the first antenna substrate and the two ends of the second antenna substrate respectively. A first Balun feeder and a second Balun feeder are insulated mutua |
