Polarization diversity and multi-frequency antenna module for DCN and SDMB band using LTCC packaging technology

摘要

In this paper, packaging antenna module of two antennas of single resonance for SDMB (satellite digital multimedia broadcasting) diversity and dual resonances for DCN (data core network) and SDMB is presented. That module is used for the package integrated with antenna and filter using the LTCC (low temperature co-fire ceramic) multilayer packaging technology. The dimension of the antenna is 12.75 /spl times/ 10.25 /spl times/ 2.2 mm/sup 3/. This module is operated at 810 MHz /spl sim/ 890 MHz and 2.61 /spl sim/ 2.73 GHz including DCN band and SDMB band, respectively. The SDMB diversity antenna in the module is operated at 2.63 /spl sim/ 2.70 GHz (VSWR<2) including SDMB band. The isolation between two SDMB antennas is 13.2 dB.
