Abstract

A patch antenna array having multiple beam-forming capability is formed as a feed network (15) on a lower microstrip substrate with patches (13) overlaying these on an upper substrate. The patch array consists of a number of linear series-connected patch arrays (13a, 13b, 13c) each array being resonant and may have open circuits at each end. A travelling wave arrangement of feed lines (15a, 15b, 15c) is provided and in one embodiment the total number of beams which may be generated is twice the number of feed lines. The invention is useful in small satellite communication earth terminals and is suitable for operation in the region of 10 GHz.
