Definitions
- the broadband circularly polarized millimeter wave multi-feed multi-beam lens antenna proposed by the present invention has the following advantages:
- Figure 8 shows the measured left-hand circular polarization and right-hand circular polarization normalized pattern when the broadband circularly polarized millimeter wave multi-feed multi-beam lens antenna excites five input ports respectively, (a) 24GHz, ( b) 26GHz, (c) 28GHz;
- the present invention provides a broadband circularly polarized millimeter wave multi-feed multi-beam lens antenna with circular polarization, wide working bandwidth, high port isolation, wide beam coverage, low cross-polarization, and beam gain
- the advantages of small fluctuations have important prospects in the future 5th generation mobile communications, satellite communications and other fields.
