A Printed antenna generating a circularly polarized conical pattern can be effectively employed as a land-mobile antenna for satellite communications. Because of the conical pattern and fairly wide beamwidth in a vertical plane, there is almost no need for tracking the satellite. The authors have presented the design of a printed antenna composed of strips and slots generating circularly polarized conical patterns. However the original design is not suitable for the application of the higher gain. In order to get the higher gain, various types of antennas with an electronically auto-tracking mechanism have been studied recently. Such antennas require phase shifters or switches to form a desired beam. In this paper, we propose a beam-switching printed array antenna composed of strips and slots.
