Disclosed herein are methods, circuits, devices, assemblies and systems for facilitating wireless communication, both satellite and terrestrial. According to embodiments, there may be provided a composite antenna structure including multiple antenna element clusters, wherein each antenna cluster may be comprised of a set of antenna elements disposed in proximity to one another and connected to one another through an intra-cluster signal distribution line. Antenna element clusters may be connected to one another and to a main signal line through a network of inter-cluster signal distribution lines. A first set of antenna element clusters may be connected to a transmission signal (TX) line, thereby forming a TX antenna. A second set of antenna element clusters may be connected to a receive signal (RX) line, thereby forming a second RX antenna. Antenna elements of RX and TX antenna element clusters may disposed on a common surface, or parallel surfaces, in an interlaced manner.
