Integrated Antenna-TR Module Design for Millimeter Band Phased-Array

In this article, LTCC (Low temperature Co-fired ceramic) is used to design integrated antenna-TR module to meet the miniaturization of phased array in ka frequency band. Integrated antenna module has lower loss between antenna and TR than normal separate antenna and TR module, and make easier to expand large array. According to multi-layer LTCC integration criterion, characters of end-fire Qusi-Yagi antenna and multi-antenans buried in LTCC materials is optimized designed, high-gain and wide-angle scanning is realized.
