This paper presents the design of two types of S‐band antennas suitable for mobile satellite communication applications. One design is based on omnidirectional radiating elements and targets consumer systems installed on cars. The other uses an array of four elements with electronic switching, controlled by embedded sensors, to generate directive beams with gain higher than the one that could be provided...
This paper presents the design of an intermediate gain S-band antenna for interactive services with electronic beam steering capabilities. The antenna allows simultaneous reception and transmission of S-band signals and can track the position of a geostationary satellite by electronically switching among a finite set of beams. The tracking system is based on combination of position and attitude sensors...
