Design of triple-band LTCC antenna using meander line structure for mobile handsets

This paper presents the design simulation of compact meander line antenna for GSM/DAB/DCS bands used in mobile handsets. The dimensions of the LTCC chip antenna are 20×10×0.85 mm
³
. The structure includes two meander patches. The bottom meander patch is tuned to GSM band, and the top meander patch is designed for DCS band. The coupling between the two meander patches is used to obtain DAB band, instead stacking a third meander patch on the two meander patches. It is found that coupling quality varies with the space between two meander patches. With the 2.5:1 VSWR impedance bandwidth definition, the lower, middle, and upper band have the bandwidth of 110, 140, and 60 MHz, respectively. This paper provides a new scheme of designing compact antenna for mobile handsets.
