The multiband microstrip patch antenna based on LTCC

A multiband microstrip patch antenna worked at BD (1.268 GHz), GPS (1.575 GHz), GLONASS(1.602 GHz) is designed by LTCC technology. A power divider matching network printed on the back with LTCC technology is used for the antenna to match the impedance. Prototype of the proposed antenna has been constructed and tested based on the calculated results of HFSS. The test results show that the antenna has a matching multiband (1.268 GHz, 1.575 GHz, 1.602 GHz). Besides, the antenna has a integrated structure and a high stability, with a Low profile (5 mm).
