“…However, this on-chip AIA is difficult to achieve high gain due to the process limitation. To improve the antenna gain, an additional off-chip reflector [3] and an additional off-chip lens [4] are introduced at the cost of increasing the size of the AIA. In [5], a Ka-band patch antenna array is integrated with packaged monolithic microwave integrated circuit (MMIC) phase shifters as an AIA using the low-temperature cofired ceramic (LTCC) technology.…”

This letter presents the design of a Ka-band active integrated antenna in package (AIAiP). A monolithic microwave integrated circuit amplifier based on the GaAs process and a compact patch antenna based on the printed circuit board process are implemented, respectively. Then, the amplifier and antenna are assembled together in a specified package using the wire-bond process. Thus, compared to the traditional solutions, the transmission loss and the size of the proposed AIAiP are significantly reduced. Furthermore, the influence of the bonding wire and the package is taken into account in the design of the amplifier and the antenna, respectively. A good agreement between the simulation and measurement results can be observed. The proposed AIAiP occupies a compact size of 7 × 7 mm 2. Meanwhile, it achieves −10-dB impedance bandwidth from 33.4 to 37.2 GHz and a peak gain of 18.9 dBi at 35 GHz. Additionally, the impact of the package size on the antenna performance has been demonstrated for future AIA designers.

INTRODUCTION A CTIVE integrated antenna (AIA) refers to the antenna integrated with one or more active solid-state devices. The AIA has received considerable interest due to its advantages in low loss and compact size, and is much more suitable for the phased-array antenna systems [1], [2]. Several kinds of AIAs
