Compact 60-GHz antenna-in-package with end-fire radiation

In this paper a 60 GHz antenna-in-package with end-fire radiation in LTCC is presented. Compared with the method mounting the chip on the side of the antenna package, the proposed antenna-in-package (AiP) configuration carries the chip on top of it to greatly save the area of RF front-end. In addition, the symmetric posts are introduced to widen the bandwidth. The metal match rings are added to smooth the S
₁₁
. The results indicate, the proposed AiP can operate from 60.4 GHz to 62.7 GHz with the maximum gain of 6.25 dBi at 60 GHz.
