Design and implementation of Broadband Antenna/Diplexer for dual-band handsets

이중대역 단말기용 광대역 안테나 및 다이플렉서 설계 및 구현

In this paper, We have designed an internal chip type-ceramic antenna and diplexer for dual-band handset applications. for increasing bandwidth, antennas used a meander line structure with L, C matching network. The designed diplexer is based on the multi-layered structure for the purpose of the LTCC applications. We have given a notch using resonator for elevated attenuation characteristics.
