Abstract
A slot antenna comprising: a first and second boards each having an edge attached to respective opposite edges of a center board to form an essentially C-shaped open-ended channel having an inner surface and an outer surface; the center board having a slot for radiating signals defined in an electrically conductive layer bonded to an outer surface thereof and an electrically conductive feed line bonded to an inner surface thereof; the slot having a drive point being a portion of the feed line undercrossing the slot between opposite edges of the slot; the first and second boards each having an electrically conductive layer bonded to an outer surface thereof to reduce nulls, thereby providing an essentially omni-directional radiation pattern for the slot; and, a connector for coupling the signals to the antenna.
