This paper presents a concept to relay sensor-detected information through satellite links. A sensor package uses a miniature continuously scanning directive-antenna to link to low-earth-orbiting (LEO) satellites with low power at pre-determined scanning steps and dwell times. Linking to geostationary satellites can also be done. Parametric plots determine the relationships between satellite altitudes,...
Two miniature phased array antenna designs that can be used in small wireless sensor packages to access satellites are presented in this paper. The antennas are designed using an array simulation program. The two models are 19- and 37-element arrays with diameters of 2.35 and 3.35 cm, respectively, operating at the Ka band frequency of 30 GHz. The antennas are well-suited for the small wireless sensors...
