Base station antennas of mobile communications are required to generate narrow vertical beam widths and wide horizontal beam widths. They are also demanded to achieve two orthogonal polarizations. Arrays of crossed dipoles are commonly used as base station antennas for mobile communications. However, they are heavy in weight, high in coast and they have a high wind resistance. Furthermore, they have limited frequency bandwidths which are not sufficient for recent expansions in mobile applications such as mobile TV and WiMax. In this research, a base station antenna that overcomes these problems has been developed using dual parabolic cylindrical reflectors. The new base station antenna covers a frequency band ranging from 450 MHz to 960 MHz with 72% bandwidth. Thus, it can cover all the bands of 450 MHz WiMax (450 MHz-470 MHz), UHF mobile digital TV "DVB-H" (470-862 MHz), 700 MHz WiMax (698-806 MHz), CDMA/GSM800 (824-894 MHz) and E-GSM900 (880-960 MHz).
