| 摘要 |
The invention relates to an improved dual polarised multi-range antenna, comprising a first and a second radiation module (1, 3) for transmitting or receiving a first frequency band and a second frequency band offset from the first. Said dual polarised multi-range antenna is characterised by the following: seen from above the antenna, the second, additional, radiation module (3) provided for the upper frequency range is located inside the dipo le square of the first radiation module (1); the second radiation module (3) consists of dipolar elements (3a) which are oriented orthogonally in relatio n to each other; the dipolar elements (3a) of the second radiation module (3) are parallel or vertical in relation to the dipolar elements (1a) of the fir st radiation module (1), forming a dipole square; and the ratio of the middle frequency of the upper frequency band to that of the lower frequency band is between 1,5 and 4. |
