CROSS-LOOP ANTENNA

摘要

An antenna is contained within a package (104) that is secured to an integrated circuit (IC 106) (which allows radiation to propagated away for a printed circuit board (PCB) so as to reduce interference), and this antenna includes two loop antennas that are shorted to ground and that "overlap" and includes a "via wall." The IC 106 has a protective overcoat (406) that covers the IC), including metallization layer 404 and IC substrate 402, and stud bumps (302-1) are secured between the IC and antenna package (104). The antenna package (104) can then be secured to the PCB. With the disclosed configuration, circular polarization can be achieved by varying the relative phases of the input signals, and the "via wall" improves efficiency by reducing surface waves.
