Design and integration of 60-GHz grid array antenna in chip package

A novel grid array antenna has been designed and further integrated as a chip-scale package in LTCC for the highly-integrated 60-GHz radios. The novel design concept and sophisticated LTCC process have guaranteed excellent performance of the grid array antenna over the targeted 7-GHz bandwidth from 57 to 67 GHz with a maximum gain of 14.5 dBi and an estimated radiation efficiency better than 90%. The antenna is being fabricated with 9 green types and gold metal in a panel size of 100x100 mm² by the LTCC Boutique Foundry in SIMTech on the NTU campus. The antenna function of the package will be tested with a probe-based measurement setup at IBM Thomas J. Watson Research Center, USA. The verified results will be presented in the APMC conference.
