    Based on low-cost PCB solution, an array antenna in packaging (AiP) dedicated for mmWave mobile systems is designed using machine learning. The proposed antenna operates at 28 GHz (26.5 - 29.5 GHz) with a gain ranging from 8 dB to 15 dB in the operating bandwidth. The development process of the proposed AiP is assisted by machine learning for prediction of the optimal radiating patch's length and width in terms of resonance frequency. © 2021 Taiwan Microwave Association.

    A Thin Dual Slot Based Offset-Fed Beam Tilted Mmwave 5g Aip Design
    (Institute of Electrical and Electronics Engineers Inc., 2021) Magray M.I.; Farouk Nakmouche M.; Tarng J.-H.; Farouk Nakmouche, Mohammed; Magray, M. Idrees; Tarng, Jenn-Hwan
    This paper presents a low profile antenna-in-package design for mmWave 5G applications. Aperture coupled feeding is incorporated with microstrip line exciting the rectangular patch radiator via two slots. The dual slots are utilized for enhancing the impedance bandwidth of antenna. A physical offset is introduced in the dual slots that is mainly done for obtaining a beam tilt towards the end-fire direction. Shorting via walls are introduced between the patch radiator and ground plane for obtaining a much higher beam tilt. Moreover, shorting vias also aid in impedance matching. The proposed antenna is wideband attaining operational bandwidth from 26 to 29.5 GHz that accounts for fractional bandwidth of 12.6%. Also, peak gain of around 7 dBi is obtained for the available aperture. Beam tilting is mainly achieved for directing radiation beam away from the broadside to end-fire direction since end-fire antennas are feasible and preferred for 5G mobile applications. © 2021 Taiwan Microwave Association.
