【 摘 要 】

The beam switching cylindrical array,which is a unique system, has been designed and developed to cover 360°in azimuth plane by generating 16 beams with specified elevationcoverage.In this design, the concept of fast aperture selection (4 x 4)in microseconds from the total cylindrical array has been realisedsuccessfully to meet the requirement of point-to-multipointcommunication. The components of the array, viz., radiating elements,powder dividers, switches, etc., are designed in printed circuit type,and hence, objectives of lightweight and ease of reproducibility areachieved. The lightweight of the array makes it accessible for easymounting at a specified height for achieving longer communication range.Finally, a low-loss radome is incorporated to protect the array fromenvironmental conditions. The various parameters, viz., return loss,gain, and switched-beam radiation patterns were measured over abandwidth of 300 MHz in L- band and typical measured results arepresented in this paper.
