Integrated antenna system with corporate feed network and antenna array

An integrated antenna system, comprising:

• a first patch, a second patch, and one or more internal patches comprising electrically conductive material, each of the first patch, second patch, and one or more internal patches having a radiator sub-patch and a feed-network sub-patch;
• wherein:
• the first patch, second patch, and one or more internal patches are co-planar;
• the one or more radiator sub-patches of the one or more internal patches are located between the radiator sub-patches of the first and second patches to form an array of tapered-slot antenna elements;
• the radiator sub-patch of each internal patch, of the one or more internal patches, tightly couples a neighboring pair of the tapered-slot antenna elements;
• the first patch, second patch, and one or more internal patches are electrically isolated from each other;
• the radiator sub-patches of the first patch, second patch, and one or more internal patches have no spatial overlap;
• the feed-network sub-patches of the first and second patches are positioned to form an initial gap therebetween and cooperate with the initial gap to create an initial transmission line;
• and
• the feed-network sub-patches of the first patch, second patch, and one or more internal patches further form a corporate feed network that is fed by the initial transmission line and feeds the array of tapered-slot antenna elements.
