Abstract

The invention provides a multi-band antenna comprising a planar substrate which in use is intended for vertical mounting, and has a bottom edge and a top edge. A conductor pattern is printed on one side of the substrate with three slots. A first slot is a U or J shape facing downwardly and a second is a U or J shape facing upwardly. A third slot extends in the vertical direction and is open at the top. A first antenna feed is coupled to a horizontal track of the second slot and a second antenna feed is coupled to the third slot. The three slots together provide multi-band performance in three bands.

First claim

The invention claimed is:

1. A multi-band antenna comprising:
a planar substrate which is configured for vertical mounting in use, and has a bottom edge and a top edge;
a conductor pattern printed on one side of the substrate and which in use is grounded at one end to a horizontal conducting plane, wherein the conductor pattern comprises a continuous conductor area having a plurality of slots defined into the area, the slots at one end opening to an edge of the conductor area, t…
