| 摘要 |
The invention relates to a square chip antenna with two crossed polarisations excited by two orthogonal slots. This antenna comprises a square metal chip (10) on a first substrate (11). Facing it on a second substrate (23) bearing a metallisation (22), two orthogonal coupling slots (20, 21) are etched. The chip is excited through the slots by two coplanar triplate lines (30, 31) which are orthogonal and are arranged at 45@ with respect to the slots. The invention applies especially to UHF array antennae. <IMAGE>
