An apparatus for enabling a base station to transmit radio frequency signals with a transmit diversity technique comprises a first antenna implemented in the base station; and a second antenna implemented in the base station, and placed apart from the first antenna by a predetermined distance. The first antenna utilizes a first frequency band of a predetermined frequency spectrum for transmitting signals, and the second antenna utilizes a second frequency band of the predetermined frequency spectrum for transmitting signals. The first and second frequency bands do not overlap. |
