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.

Horizontally polarized slot antenna with omni-directional and sectorial radiation patterns

A high gain printed loop antenna comprises a first and second loop arranged symmetrically about a feed network, wherein each of the loops include pairs of substantially parallel radiation sections which when excited in phase from the feed network improves the gain of the antenna. Each of the parallel radiation sections are joined by patch elements such that the width of the patch elements is greater than the width of other portions of the loop. Thus, the patch elements allow for an increased variance in the path of a surface current through the loop.

High gain printed loop antenna

A printed antenna comprising a dielectric substrate, dipole elements formed on a surface of the substrate, a matching network for coupling a driving point to the antenna elements, whereby common mode currents are minimized thereby minimizing the antenna performance degradation.
