Summary form only given. In this invited talk, the millimetre-wave (mmW) antenna arrays which are fully integrated into low-temperature co-fired ceramic (LTCC) with substrate integrated concept are reviewed. We start with addressing the important challenges in designing mmW antennas such as losses, fabrication, and measurement. After that, three typical designs are introduced as examples. A 60-GHz antenna array with greatly reduced loss caused by surface waves is first introduced. With the proposed cavity technique, the gain of the array increases by up to 2 dB. Second, a broadband high-gain 60-GHz LTCC array is shown. The multiple layered LTCC substrate provides more freedom to integrate the array and feeding network in substrate with much low insertion loss and consistent radiation patterns using parallel feeding structures. Finally, the design and measurement of a 140GHz LTCC antenna array is reported. The challenges related to fabrication and measurement is highlighted.
