    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.
