INTEGRAGTED DUAL BAND H-FIELD SHIELDED LOOP ANTENNA AND E-FIELD ANTENNA |
摘要 |
A dual band antenna system that combines into a single integrated device an H-field shielded loop antenna and an E-field antenna. The system includes an unshielded section bounded on each end by first and second shielded sections, respectively. Input frequency filters are electrically connected to the first shielded section t o selectively pass one of a first radio frequency signal or a second radio frequency signal through the first shielded section. Output frequency filters electrically connected to the unshielded section for switching between two paths of transmission and associated modes of operation: (i) a first mode (operating as an H-field antenna) in which an H-field transmission pattern is generated in the first and second shielded sections; and (ii) a second mode (operating as an E-field antenna) wherein an E-field is radiated via the E-field antenna.< /SDOAB>
