Claim Text:
1. An active antenna ceiling assembly comprising: a ground plane structure comprising a plurality of ground plane tiles without an antenna layer, wherein each ground plane tile comprises an electromagnetically reflective layer; and an active antenna tile having the same approximate area as a ground plane tile from the plurality of ground plane tiles, the active antenna tile comprising: a first dielectric layer; an antenna layer comprising a number of antennas configured to receive and transmit radio frequency (RF) signals, the antenna layer disposed on the first dielectric layer; and a ground plane layer disposed above the antenna layer and in electrical communication with the ground plane structure, wherein a ratio between the number of ground plane tiles and the number of active antenna tiles is greater than or equal to 8 to 1; wherein the active antenna tile further comprises a second dielectric layer disposed between the antenna layer and the first ground plane layer; and wherein the active antenna tile further comprises a bidirectional power divider in electrical communication with at least two antennas of the number of antennas.
