Abstract

The present invention relates to a patch antenna constructed in a multi-layer substrate, comprising an antenna surface, i.e. a patch (10), an antenna feeder (8) extending from a signal source to said patch, and an earth plane (9) disposed parallel with the patch but in spaced relationship therewith, wherein the antenna feeder is generally parallel relative to the patch but disposed in a different layer to the patch, and wherein the end (17) of the antenna feeder is located inwardly of the periphery of the patch (10). The invention is characterised in that the antenna feeder (8) and the earth plane (9) are placed on mutually different sides of the patch (10); and in that an additional earth plane (11) is disposed between the antenna feeder (8) and said first mentioned earth plane (9), for co-action with the antenna feeder.
