Abstract :
The performance of a simple beam-switching four-patch array antenna, radiating circular polarization at 2.6 GHz, is presented. This antenna generates a directive beam allowing the tracking of the signal emitted by a satellite. Two methods of feeding the antenna, to realize the beam-tracking, are analyzed. First, when the feeding source is switched off. Second, when one element is fed with a different phase than the others. This four-patch array antenna has good performances in terms of minimum gain, axial ratio and voltage standing wave ratio but also small size and low cost.
