The utility model provides a two polarized radiation oscillators and multifrequency multiport antenna device, this antenna device include the principal reflection board, set up in on the principal reflection board at least two polarized radiation oscillator arrays and at least one be listed as the high -frequency oscillation array, wherein, each row in the at least two polarized radiation oscillator arrays satisfy following condition including at least one two polarized radiation oscillator: three oscillator arm has, three oscillator arm is " perpendicular to " font level to be placed perpendicularly, one of them oscillator arm and with it adjacent two other oscillator arms become 90 respectively and place perpendicularly, and carry out the feed between every two adjacent orthogonal oscillator arms, form + 45 the degree polarization. Multifrequency multiport antenna device has improved the flexibility of combination between the oscillator owing to adopted the structure of above -mentioned pair of polarized radiation oscillator, just can realize owing to three oscillator arm only needs two distributing points + 45 degree double polarization characteristic has been simplified the structure of two polarized radiation oscillators.
