| 摘要 |
The present invention relates to a microstrip sector antenna (1 ) of polarization substantially parallel to the longitudinal axis thereof having a housing (2) in which a metal shielding layer (5) is disposed, wherein above said shielding layer at least one dielectric plate (4) is disposed over which a microstrip structure (3) is disposed, said microstrip structure having at least two radiating elements (31 ) arranged substantially parallel to the longitudinal axis of the antenna. Each of said radiating elements (31 ) has at least two substantially longitudinal radiating patches having longitudinal axes inclined substantially at the same and acute angle relative to the longitudinal axis of the antenna (1 ), wherein said patches are electromagnetically coupled by their end portions with the main feed path (32) of the antenna (1 ) by means of additional feed paths. |
