Internal radio transceiver antenna, for mobile telephone, has separate transmit/receive antennas on one dielectric block mounted on circuit board

摘要

The transceiver antenna diplexer has a transmit antenna (16) and filter (14) on the same amorphous dielectric substrate (12) as a receive antenna (22) and filter (20). The filters are separated by a gap (100) in which the earth metallization (44) is included.
