Abstract: Terrestrial antennas (10A, 10B and 10C) which are capable of transmitting and receiving radio signals directly to and from satellites in low Earth orbit are disclosed. The preferred embodiments of the invention employ printed circuit antenna elements (18) measuring only a fraction of an inch (less than 2 cm) in diameter. One embodiment (10A) includes an elevation array residing on a circular surface (14) and an azimuth array residing on a conical surface (12). This first embodiment (10A) resembles a flattened pyramid. Both the top and the curved exterior of the pyramid support circular, slotted, printed circuit patches (18). Other embodiment of the invention employ hemispherical (10B) or cylindrical (10C) configurations.

Abstract: The disclosed satellite communication system comprises a dynamic constellation (C) of satellites (S). The system includes a number of low-earth orbiting spacecraft (S) which travel in orbital planes. Each of the individual spacecraft (S) functions as an independent sovereign switch which knows the position of its neighbors, and independently handles traffic without ground control. The satellites (S) are capable of transporting calls directly to users of portable, mobile and fixed radio terminals; and via gateways to users of the public switched telephone network. The present invention offers direct communication between satellites (S) of the constellation (C) and individuals using lightweight, portable telephones. The direct link is made possible by miniature antennas (210) coupled to the handheld phones.
