Shaped reflector antennas for outdoor BTS of 4G/5G mobile communications

This paper presents an effective design of reflector antennas to radiate beam patterns fulfilling the coverage need of base station antenna (BSA) system in the 4G/5G mobile communication. A mechanical feed's titling mechanism has been implemented in conjunction with the synthesis of reflecting surface to provide remote beam tilting function for dynamic cell adjustments. The numerical and experimental results are shown to demonstrate the design concept.
