| 摘要 |
The present invention relates to an antenna (20; 80) comprising a patch element (21; 83), a conductive base plate (22; 82) essentially parallel with said patch element, where said patch element is provided with at least one feed means (26; 89) to provide circular polarisation, wherein said patch element has a first opening arranged essentially in the centre of said patch element (21; 83), said conductive base plate has a corresponding second opening arranged opposite to said first opening, and said antenna further comprises a conductive connection (25; 85) connected between said first and second openings periphery, thus creating a hole (24; 84) through said antenna, where said hole (24; 84) is adapted to be used for at least one function not being an antenna function. A capacitive load may also be provided between the edge (21') of said patch element (21; 83) and said conductive base plate (22', 22; 82). The invention also relates to a communication device (30; 62) comprising such an antenna (35; 61). |
