This article presents an integrated packaging antenna-diplexer module for wireless communication system in the cellular and satellite digital multimedia broadcasting (SDMB) band. Multilayer low temperature cofired ceramic (LTCC) technology with integration capability was used in design and fabrication of the proposed module. To achieve a compact integration, an inverted-F antenna UFA) with a meander line and a diplexer composed of low-pass filler (LPF) and high-pass filter (HPF) was embedded. The proposed module with dimension of 27.5 x 12.0 x 2.2 mm3 operates over a range from 813 to 902 MHz for the cellular hand and from 2586 to 2655 MHz for the SDMB band. An isolation level below -25 dB was obtained at each band. The measured gains of the fabricated module are -1.96 and -5.43 dBi, respectively.
