BROADBAND ANTENNA AND RADIO BASE STATION SYSTEM FOR PROCESSING AT LEAST TWO FREQUENCY BANDS OR RADIO STANDARDS IN A RADIO COMMUNICATIONS SYSTEM

摘要

The present invention refers to a broadband antenna configured for processing at least two frequency bands or radio standards in a radio communications system the broadband antenna comprising at least one column the column comprising at least one antenna element a first phase shifter configured for phase shifting a first frequency band or radio standard and a second phase shifter configured for phase shifting a second frequency band or radio standard and a diplexer configured for diplexing the phase shifted first and second frequency bands or radio standards comprising two inputs and one output with the first phase shifter and the second phase shifter being coupled to the two inputs and the antenna element being coupled to the output. The invention further refers to a radio base station system comprising a broadband antenna according to the invention.
