Abstract (en)
A feed structure for use in a wireless communication system for transmitting and receiving a data signal. The feed structure (10) includes a dielectric substrate (12) having a lower surface (16) upon which a conductive material is disposed, an upper surface (14), and an edge (18). A plurality of slot radiators (20), each having a wide end (22) coterminous with the edge (18) and a narrow end (24), is etched into the conductive material. A switching mechanism is provided for connecting the narrow end of a selected slot radiator to an input bus containing a signal so that a relatively narrow beam is caused to propagate from the wide end of the selected slot radiator. <IMAGE>
