CROSS-LOOP ANTENNA

摘要

An antenna is provided. This antenna is contained within a package that is secured to an IC (which allows radiation to propagated away for a printed circuit board 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. With this 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.
