Broadband monopole antenna in uniplanar printed circuit technology and transmit- and/or receive device with such an antenna

摘要

The antenna includes a feed line (2) which is positioned on the first surface of a substrate. A conductor (3) is positioned on the second surface to form a ground plane (4) for the RF feed. A radiating stub (6) extends at least partially along the length of the side of the ground plate. A coupling slot (7) is formed between the stub and the plate. The coupling slot crosses the supply line at a crossing point beyond which the supply line has a series stub of a first adaptable length and the slot forms a parallel stub of a second adaptable length. The slot can be rectangular and the stub have variable width.
