FILTER TECHNIQUE FOR INCREASING ANTENNA ISOLATION IN PORTABLE COMMUNICATION DEVICES |
摘要 |
Provided is a system and method for eliminating the effects of antenna coupling by increasing the isolation between closely mounted antennas on a portable wireless communications device. Increased isolation is achieved by providing a ceramic resonator in the path of each of the antennas. The ceramic resonator placed in the path of a particular antenna eliminates the effects of coupling caused by a particular one of the other antennas by rejecting signals associated with the particular antenna.
