Abstract:
A distributed antenna for use in digital mobile communication systems comprising:(1) at least one RF transmission means to couple RF signals receiving from and transmitting to a base station, wherein said RF signals are in the form of down-link RF signals, and up-link RF signals, respectively; (2) two divider means which divide the down-link RF signals and the up-link RF signals into more than two RF signal directions; (3) combiner means coupled to one of said RF signal directions from said divider means and including at least one transmitter and receiver pair to detect and convert said RF signals into base band signals and to modulate said base band signals into new RF signals by interconnecting said base band signals from said receiver to said transmitter to repeat the new RF signals to and from said divider means; (4) built-in antenna means coupled to said combiner means; and (5) at least one RF transmission means to couple another of said RF signal directions from said divider means with a next stage of said distributed antenna.
